Title:
__nih_abort_msg symbol cannot be read any more
Status in gcc-5 package in Ubuntu:
New
Status in libnih package in Ubuntu:
Invalid
Bug description:
libnih has a global symbol __nih_abort_msg that contains the message
of the last failed nih_assert() (similar to glibc's own __abort_msg
and glib's __glib_assert_msg). Apport uses these to produce a more
meaningful crash report than just "/bin/foo crashed with SIGABRT", as
in these case the thing you actually want to see is the assertion
message.
This stopped working in yakkety/amd64. apport's
report.test_add_gdb_info_abort_libnih() now fails:
ERROR: test_add_gdb_info_abort_libnih (__main__.T)
add_gdb_info() with libnih assertion
----------------------------------------------------------------------
Traceback (most recent call last):
File "./test_report.py", line 886, in test_add_gdb_info_abort_libnih
self.assertIn('Assertion failed in main: 1 < 0', pr['AssertionMessage'])
File "/usr/lib/python3.5/collections/__init__.py", line 985, in __getitem__
raise KeyError(key)
KeyError: 'AssertionMessage'
This can be reproduced with the attached script which compiles a
trivial nih_assert() C program, runs it, and runs gdb on the produced
core dump. Up until xenial it looks like:
$ ./nih-assert.sh
(null):<stdin>:2: Assertion failed in main: 1 < 0
Aborted (core dumped)
[New LWP 9838]
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `./nih-assert'.
Program terminated with signal SIGABRT, Aborted.

$1 = 0x25400f0 "<stdin>:2: Assertion failed in main: 1 < 0"
But in yakkety/amd64 it now looks like
$ ./nih-assert.sh
(null):<stdin>:2: Assertion failed in main: 1 < 0
Aborted (core dumped)

$1 = 0xffffffff869400f0 <error: Cannot access memory at address

This can be reproduced easily in a schroot, you need to install "libnih-dev
pkg-config gdb".
