problem with malloc in gcc-3.2.2
Hi all,
int
main ()
{
int *p;
int i;
p = (int *) malloc (400 * sizeof (int));
for (i = 0; i 512; i++)
{
p[i] = i;
printf (p[%d]: %d\n, i, p[i]);
}
return 0;
}
The following code should terminate with Segmentation fault, right ?
But when I tried, it works even beyond the limits of allocated area ...
I am using Glibc - 2.3.2-11.9 , gcc - 3.2.2
Is it a bug - malloc's implementation in Glibc.
Does malloc allocates a complete 4k page for certain size of memory asked for?
Infact, it gives a segmentation fault at 1681 location =
p[1681]: 1681
Segmentation fault
Or is it using Heap area ?

Regards,
Sandeep

[Bug testsuite/23400] [4.1 Regression] make check fixinclude failure
--- Comment #6 from rep dot nop at aon dot at 2005-11-20 13:26 --- Created an attachment (id=10300) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=10300action=view) Add newline to replacement fixup for string.h I wouldn't generally add a newline in the replace command but adjust the fixups which expect the newline to contain a newline in the replacement text. The following patch gcc.gfortran-pr23400-00.diff adds a newline to the string replacement which fixes the fixincludes failiure for me on i686-linux-gnu on debian unstable. gcc.gfortran-pr23400-00.diff 2005-11-20 Bernhard Fischer [EMAIL PROTECTED] PR 23400 * inclhack.def: Add newline to the replace text for string.h. * fixincl.x: Regenerate. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23400

--- Comment #2 from pcarlini at suse dot de 2005-11-20 13:37 --- (In reply to comment #1) There is no correct output when you use a variable uninitialized. It's undefined behavior. Printing any number, or crashing, would be completely valid behaviors as far as gcc is concerned. Falk, of course you are right. However, when I saw the PR coming, I wondered whether the point was also that it would be nice having the warning emitted also at low optimization levels. Other compilers can do that, AFAIK. Maybe we already have something open about that, tough, as enhancement request. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24956
[Bug regression/24956] Optimizer and uninitialised variables.
--- Comment #3 from s_a_white at email dot com 2005-11-20 14:15 --- Sorry the summary may not be 100% correct, but it is related to the variable never being directly assigned. I do understand that using (i.e. assigning from an unintialised variable) will give you random junk, etc. However if you look at the example below you'll see the variable becomes fully assigned (the result is always known given a uint_least32_t being 32 bits). And indeed the first printf does display the correct answer. However whats happened is that some of the code inside the if statement has executed, which is should never have! Please if this code is actually invalid... and indeed somehow the code inside the if statement can legally be executed please could you reclose the bug and drop me a note on why? So far have never seen even highly optimising compilers (e.g. TI c6x, etc) do this. -- s_a_white at email dot com changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|INVALID | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24956

--- Comment #4 from falk at debian dot org 2005-11-20 14:35 --- I already explained this. Using an uninitialized variable invokes undefined behavior. This means that producing random junk, executing random if statements, executing random if statements 17 times, formatting your hard disk, and making demons fly out of your nose are all perfectly valid results. The concept of undefined behavior should be explained in any C book. -- falk at debian dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24956

I also found the same problem with a friends fedora core 4 with gcc 4.
I have attached a cpp file that (I believe) should compile (and does on
Borland c++). It is the copy at the end that causes a problem - the
while loop is simply doing the same as what the copy should do (just to
show I did the operator properly). Copy works for other cases (ints,
floats, etc) and even for my own structs too. I'm just not sure why it
complains about the operator function for a std::pair.

[Bug target/24961] New: No constraint letter for destination_operand
There is no way to specify a constraint for an operand of an asm statement that may only be a destination operand (ie. the first operand of the st insn). If you try to use the m constraint together with the %P operand modifier you can get invalid asm code when %P expands to a register instead of a number. For example, the Linux kernel uses this asm statement: asm volatile (\n[1:]\tst#n %1=%r2%P1\t// %0 gets overwritten by exception handler\n \t.xdata4 \__ex_table\, 1b-., 1f-.\n [1:] : =r(__pu_r8) : m(__m(addr)), rO(val), 0(__pu_r8)); Occassionally you'll get an assembler error because the POST_MODIFY is expanded into a register. -- Summary: No constraint letter for destination_operand Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: schwab at suse dot de GCC target triplet: ia64-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24961

--- Comment #8 from nathan at gcc dot gnu dot org 2005-11-20 19:29 --- I've come to the conclusion that my 21166 patch was overzealous. What I now think is that packing a decl always changes its type except for one case described below. Even when the field's placment happens to work out right, the decl should remain packed (it's just an accident of placement, which is fragile). The exception should be were BITS_PER_UNIT == TYPE_ALIGN (TREE_TYPE (field)). Packing such a field is a no-op, so should not be reflected in the type system. We can place this check when we first attempt to set DECL_PACKED. I think this is sufficient to fix the original problem 21166 was trying to solve. -- nathan at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |nathan at gcc dot gnu dot |dot org |org Status|WAITING |ASSIGNED Last reconfirmed|2005-10-22 06:56:58 |2005-11-20 19:29:49 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23304

Re: C++ bug with std::copy and std::pair
Hi, I have attached a cpp file that (I believe) should compile (and does on Borland c++). It is the copy at the end that causes a problem - the while loop is simply doing the same as what the copy should do (just to show I did the operator properly). Copy works for other cases (ints, floats, etc) and even for my own structs too. I'm just not sure why it complains about the operator function for a std::pair. The short answer is that the behavior implemented by GCC is correct, according to the ISO C++ Standard. Of course I agree that it's somewhat unexpected: you may want to have a look to this thread, for instance: http://tinyurl.com/dtxrx Paolo.

--- Comment #1 from pinskia at gcc dot gnu dot org 2005-11-21 00:40 ---
This comes down to the tree-combiner.
Take the following C functions:
double fabs(double);
double f(double a)
{
return fabs(a)*fabs(a);
}
double f1(double *a)
{
return fabs(*a)*fabs(*a);
}
double f2(double *a)
{
double t = fabs(*a);
return t*t;
}
Only f2 is not optimized.

--- Comment #6 from gdr at gcc dot gnu dot org 2005-11-21 02:09 --- (In reply to comment #5) I've made a small amount of headway on this. Labels L22 and L21 were (when created) the addresses of objects in the code. However, they are deleted (presumably as unreachable), but the references to the lables persist. This is presumably exactly the case that RTH believed couldn't happen when he mentioned this in his email here: http://gcc.gnu.org/ml/gcc-patches/2000-05/msg00881.html and the reason we don't abort on ARM is that we never call output_constant_pool since we roll our own mini-pools.
