Package: libc6
Severity: important
This may turn out to be a gdb bug, but let's start here...
asuffield@cyclone:~$ cat foo.c
int main(void)
{
abort();
}
asuffield@cyclone:~$ gcc -o foo foo.c
asuffield@cyclone:~$ ./foo
Aborted (core dumped)
asuffield@cyclone:~$ gdb foo core

Note how when using the NPTL version of the library, the stack trace
does not contain the caller of abort() or anything that preceeded it;
this makes abort() mostly useless, and the generated core dump
entirely useless.
