Oops, gaim was a bad example; I had installed the debugging libraries
just that night :)
But still, it doesn't work forme. I don't know about ELF internals,
but GDB and catchsegv can both give a stacktrace even when compiling
without -g, and even when the source file is unavailable.
Yet pstack doesn't even DWIW when I compile with -g, and gives a bogus
error about opening the object file (why does it want the object
file!? This happens even if the .o is available (make sleep.o && make
sleep).
$ cat sleep.c
#include <unistd.h>
int main()
{
sleep(999);
return 0;
}
$ make CFLAGS='-W -Wall -g' sleep
cc -W -Wall -g sleep.c -o sleep
$ ./sleep &
[1] 19029
$ pstack 19029
19029: ./sleep
'': opening object file: No such file or directory
Could not open object file.
It tries this:
open("", O_RDONLY) = -1 ENOENT (No such file or directory)
which is apparently the result of reading the /proc/$pid/exe file and
then ptrace peeking at the processes address space.
I consider this a bug .. I'm very interested in figuring it out
though. So I'm finally sending this off instead of letting it bitrot
and clutter my mailbox; I hope to look at it sometime soon..
