Crash interception/debugging systems like Apport or ABRT capture core dumps for later crash analysis. However, if a program exits with an assertion failure, the core dump is not useful since the assertion message is only printed to stderr. glibc recently got a patch which stores the message of assert() into the __abort_msg global variable. (http://sourceware.org/git/?p=glibc.git;a=commitdiff;h=48dcd0ba) That works fine for programs which actually use the standard C assert() macro. This patch adds the same functionality for glib's assertion tests. If we are building against a glibc which already has __abort_msg (2.11 and later, or backported above git commit), use that, otherwise put it into our own field __glib_assert_msg. Usage: $ cat test.c #include <glib.h> int main() { g_assert(1 < 0); return 0; } $ ./test **ERROR:test.c:5:main: assertion failed: (1 < 0) Aborted (Core dumped) $ gdb --batch --ex 'print (char*) __abort_msg' ./test core [...] $1 = 0x93bf028 "ERROR:test.c:5:main: assertion failed: (1 < 0)" https://bugzilla.gnome.org/show_bug.cgi?id=594872
