Description Matthias Clasen 2009-12-22 14:29:41 UTC

Recent glibc (2.11, in current rawhide) store assertion messages into the variable __abort_msg before aborting. This is very useful information that abrt should extract and place prominently in the bug report.

Soon glib's g_assert facility will employ the same mechanism. 
See https://bugzilla.gnome.org/show_bug.cgi?id=594872


Here is how it works:

[mclasen@planemask Desktop]$ cat test.c
#include <assert.h>

int main (int argc, char *argv[])
{
  assert (1 < 0);
}

[mclasen@planemask Desktop]$ make test
cc     test.c   -o test

[mclasen@planemask Desktop]$ ./test
test: test.c:5: main: Assertion `1 < 0' failed.
Aborted (core dumped)

[mclasen@planemask Desktop]$ gdb --batch --ex 'print (char*) __abort_msg' ./test core.3618 
Core was generated by `./test'.
Program terminated with signal 6, Aborted.
#0  0x0000003addc326c5 in raise (sig=<value optimized out>)

$1 = 0x1fe2080 "test: test.c:5: main: Assertion `1 < 0' failed.\n"

Done so in git, will be in 1.0.4

Comment 3 Matthias Clasen 2010-01-25 23:31:09 UTC

Thanks for implementing this !

Unfortunately, it turns out that making glib2 use the variable for its assertion messages does not work out (since the glibc symbol is marked as GLIBC_PRIVATE, and rpm won't let us add a dependency against such symbols to glib2). Therefore, glib2 will have to use its own variable, __glib_assert_msg, for this purpose. Can I ask you to include that variable in abrt reports as well, at least for binaries that link against libglib-2.0.so ?

Comment 4 Fedora Update System 2010-01-26 01:06:36 UTC

abrt-1.0.4-1.fc12 has been pushed to the Fedora 12 stable repository.  If problems still persist, please make note of it in this bug report.

Comment 5 Matthias Clasen 2010-01-27 15:10:19 UTC

Hmm, reopening again. See comment 3.

Comment 6 Matthias Clasen 2010-01-27 15:17:58 UTC

Just to clarify:

in current rawhide, assert() and friends in glibc store their message in __assert_msg, while g_assert() and friends in glib2 store their message in __glib_assert_msg. We are currently investigating if we can somehow make glib use __assert_msg in some other way.

Comment 7 Denys Vlasenko 2010-01-29 15:55:43 UTC

Waitasec. Is it __assert_msg or __abort_msg?

Comment 8 Matthias Clasen 2010-01-29 18:15:37 UTC

__abort_msg and __glib_assert_msg are the correct names. Sorry for the confusion.

Comment 9 Denys Vlasenko 2010-02-03 11:56:52 UTC

fixed in git.
