--- Comment #4 from simon dot marshall at misys dot com 2008-02-19 12:04 --- OK, before I start hacking, what is it that you need once I have found a function? What I can do is try to identify a function or minimal functions that, when compiled in a file with optimisation, will cause Emacs to detect inconsistent internal state, but not when compiled without optimisation. I can compile this file with -g -O0 -fno-unit-at-a-time, -g -O1 -fno-unit-at-a-time and -g -O2 -fno-unit-at-a-time. I can compile all other files with -g -O2 -fno-unit-at-a-time. Does this sound right? Once I've found it, what would be useful to you? Output from -E for that file? Files generated by -S for that file using the flags above? Some other internal gcc output?

intervals2.c and output of -v -save-temps
Maybe it was easier than I thought. I took out the function update_interval
from the file internals.c, in which Emacs was detecting internal data structure
inconsistency, and compiled it in a new file internals2.c. With this separate
file, I can reproduce the error if I build with -g -O1 -fno-unit-at-a-time or
-g -O2 -fno-unit-at-a-time, but not with -g -O0 -fno-unit-at-a-time.
Attached is the output generated by -v -save-temps -g -O1 -fno-unit-at-a-time
for this file, ie, the .c, .i, .s and the output of gcc itself. All other
files in the Emacs executable were compiled with -g -O2 -fno-unit-at-a-time.
The offending call of error occurs at internals.c:34:
else if (NULL_PARENT (i))
error (Point before start of properties);
which according to internals.i is:
else if (((i)-up_obj || (i)-up.interval == 0))
error (Point before start of properties);
Note the condition that needs to be true for error to be called. However, when
error is called:

So, if the data appears to suggest that the condition should be false, why does

Or did I do something stupid? Is this really a symptom of some other problem?

[Bug libgcj/35253] New: reflection on annotation objects throws IllegalAccessException
The following test program throws an IllegalAccessException with gij,
but works with Sun Java.
~$ gij InvokeAnnotationMethod
Exception in thread main java.lang.IllegalAccessException
at java.lang.reflect.Method.invoke(libgcj.so.90)
at test.Helper.invoke(Helper.java:11)
at InvokeAnnotationMethod.main(InvokeAnnotationMethod.java:11)
~$ java InvokeAnnotationMethod
~$ java -version
java version 1.6.0
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)
The odd thing is that if the test.Helper class below is moved up to
the default package, the program works. So there seems to be some
reflection bug.

fwiw the real loop i pulled this fragment from has a bit more dependent on

We should recognize that the latter template is more specialized than the
former, and so the implicit address of cyl_bessel_jint, double is
unambiguous.

[Bug c++/34950] [4.2/4.3/4.4 Regression] ICE in svn boost math toolkit
--- Comment #21 from jason at gcc dot gnu dot org 2008-02-19 22:13 --- On second thought, the testcase seems to be well-formed; we should do partial ordering and determine that the second template is more specialized than the first. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34950

--- Comment #20 from jason at gcc dot gnu dot org 2008-02-19 21:45 --- Incidentally, the error that 3.3 gave for the testcase in comment #8 seems to be correct: after we substitute the explicit args into the two function templates, we are left with one which still has an unbound argument, which I believe makes it an undeduced context under [temp.deduct.type] paragraph 5 (the set of functions provided as an argument contains one or more function templates). The EDG compiler seems to disagree, so this should probably become a core language issue. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34950

[Bug target/35258] New: two memcpy calls merged incorrectly with -O1
Someone at IBM working on a very large project on s390 showed me some odd code
in which two memcpy calls get merged into something that instead spreads one
character into the final destination. A modification of that code that looks
more normal is:
char string2[9] = 1234;
void
foo (void)
{
char temp[4];
char *p = string2[2];
memcpy (temp, string2[1], 4);
memcpy (p, temp, 4);
string2[1] = '.';
}
The result in string2 should be 1.234 but is 1. (or so says the person
who reported this to me). I'll attach the full test case with both versions of
the code.
Based on my examination of the generated s390 code, which I had never seen
before and just barely understand, this was broken in 3.0 through 3.4, OK in
4.0 through 4.2, and is broken again in 4.3.
