It's also worth noting that running strings on the core file does reveal
the contents of the assertion message.
$ strings core
....
CORE
main: assertion 1 < 0): (1 < 0)
sertion failed (
LINUX
main: assertion 1 < 0): (1 < 0)

Title:
print of __glib_assert_msg not returning a message
Status in apport package in Ubuntu:
New
Status in gdb package in Ubuntu:
New
Bug description:
apport's test test_add_gdb_info_abort_glib has been failing for a bit,
since zesty(?), now. Digging into this matter I discovered that using
gdb to "print __glib_assert_msg" is resulting in different behavior.
With the generated binary, it used to return the following:
$2 = 0x7fadc0 "ERROR:<stdin>:2:main: assertion failed (1 < 0): (1 <
0)"
However, now I am seeing:
(gdb) print __glib_assert_msg
$1 = 1332592064
(gdb) print (char*) __glib_assert_msg
$2 = 0x4f6dbdc0 <error: Cannot access memory at address 0x4f6dbdc0>
This seems to be a regression in gdb itself, I've added an apport task
though to track the disabling of the autopkgtest which utilizes this
command.
