[Bug c++/67650] undef reference with -fdevirtualize
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67650 Jonathan Briggs changed: What|Removed |Added CC||zlynx at acm dot org --- Comment #12 from Jonathan Briggs --- This looks incredibly similar to a bug I found this week compiling my code with GCC 6.0. My code was much more complex, which has made it really difficult to write a small reproducer, but I also have a virtual function that is overriding an abstract base class. The implementation function is defined inline and is part of a template class. In code compiled with O2 or O3 the function call and all following code simply disappears from the assembly.

--- Comment #10 from zlynx at acm dot org 2009-08-15 00:02 --- I erased every trace of experimental GCC versions and support libraries. Then I rebuilt GCC 4.4.2 (from SVN) using the system provided GCC 4.3. The problem went away. It still worries me some because it seems to indicate that the GCC bootstrap process was not pure and was somehow using a bad version of GCC or libraries. -- zlynx at acm dot org changed: What|Removed |Added Status|WAITING |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40841

--- Comment #9 from zlynx at acm dot org 2009-07-27 21:26 --- I built GCC using libunwind and binutils 2.19.1 and there is the same problem. The registers are *not* being restored to the right values after the exception return. In the following assembly code you can clearly see that it expects the value in r37 to remain useful after the call to f. It doesn't. mov r37=r1 addl r38=112,r1;; ld8 r38=[r38] nop.i 0x0 nop.m 0x0 nop.i 0x0 br.call.sptk.many b0=4f80 f(char const*) mov r1=r37 nop.i 0x0 br.few 40001210 main+0x190;; (Well, ok, it actually jumps to the exception catch block, but that block also does mov r1=r37 to get a PLT offset.) -- zlynx at acm dot org changed: What|Removed |Added Known to fail||4.4.1 4.4.2 Known to work||4.3.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40841

[Bug libstdc++/40841] New: Application segfaults when throwing an exception that destroys an fstream
I configure the fstream like this:
ifstream is;
is.exceptions(ifstream::badbit | ifstream::failbit);
is.open(filename, ifstream::in | ifstream::binary);
When it tries to open a file that does not exist, it throws an exception just
as it should. If this is immediately inside a try/catch block it works. If it
is inside a function call however, the program segfaults.
I believe that the problem is inside the ifstream class. Further testing showed
that declaring a function like this:
void f() {
ifstream is;
throw 1;
}
also causes a segfault.
If the exception is not caught in the functions above f() there is an exception
abort but no segfault.
I tried this on GCC 4.4.1 and 4.4.2, both from SVN. GCC 4.3 from Fedora does
not do this.
I believe that the problem is in the libraries, not the GCC binary, because the
Fedora GCC *does* show the problem if I allow it to link to the libraries from
GCC 4.4.2. A -static build on GCC 4.3 works, and a -static build on GCC 4.4.2
fails.

--- Comment #5 from zlynx at acm dot org 2009-07-23 22:26 --- The actual segfault seems to happen in the .plt section. I am not entirely clear on how this is laid out and how to find what symbol is where. But on entry to the plt code, the r1 register is set to an invalid memory location and it is then read from. It appears that r1 is supposed to be set from r35 much earlier, perhaps it gets overwritten. It sort of looks like the exception unwinder changed the register value but the code expects the register to still hold the right offset to the PLT. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40841

I think you missed some of your explanation.
Do you mean that it may not be valid to take the address of a global struct
with partial definition? For example in udns_init.c which does not define
dns_defctx, but has this code:
int dns_init(struct dns_ctx *ctx, int do_open) {
if (!ctx)
ctx = dns_defctx;

[Bug libstdc++/35763] New: std::cout loses whole blocks of output if interrupted by signal without SA_RESTART
I noticed this when running a program that uses a periodic timer signal. The sigaction did not set SA_RESTART. During program runs, huge chunks of console output would disappear. I sort of tracked this down to the code in libstdc++ that uses fwrite to do the output of cout and cerr. That is a bit weird, I expected it to be using the basic_file operations on fd 0 instead. In summary, it appears to call fwrite and never check the error return, then it increments the streambuf pointers and loses that whole output block. -- Summary: std::cout loses whole blocks of output if interrupted by signal without SA_RESTART Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: zlynx at acm dot org GCC host triplet: x86_64-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35763

[Bug tree-optimization/20474] New: ICE while compiling openmotif-2.2.3 with -ftree-vectorize
I was updating my Gentoo installation with the latest and got an internal compiler error in openmotif. This happened first with Gentoo's GCC version 4.0.0_beta20050305. I then CVS'd the latest GCC version and got the same error with that. gcc version 4.1.0 20050314 (experimental) configured with: ../configure --prefix=/opt/gcc-4.0 --with-system-zlib --disable-checking --disable-werror --disable-libunwind-exceptions --disable-multilib --with-gcc-version-trigger=/home/lynx/Desktop/working/gcc/gcc/version.c --enable-languages=c,c++,java,objc : (reconfigured) ../configure --prefix=/opt/gcc-4.0 --with-system-zlib --disable-checking --disable-werror --disable-libunwind-exceptions --disable-multilib --with-gcc-version-trigger=/home/lynx/Desktop/working/gcc/gcc/version.c --enable-languages=c,c++ How-To-Repeat: Command: # gcc -O3 -ftree-vectorize pack.c Output: pack.c: In function 'PackString': pack.c:865: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
