--- Comment #9 from Martin Liska <mliska at suse dot cz> ---
Hm, on x86_64 (on trunk) I see all tests OK, but:
$ ./backtrace-dwarf
backtrace-dwarf: backtrace-dwarf.c:146: main: Assertion `errno == 0' failed.
0x7ffff7a4f08b raise
0x7ffff7a384e9 abort
0x7ffff7a383c1 __assert_fail_base.cold.0
0x7ffff7a476f2 __assert_fail
0x40135a main
which should not happen. On my machine I see errno == 2.
I would expect the test will fail with:
diff --git a/tests/backtrace-dwarf.c b/tests/backtrace-dwarf.c
index e1eb4928..273d2b5e 100644

but it's still fine, while:
./backtrace-dwarf

failed.
Aborted (core dumped)
That said, the tests looks to me very fragile..
