Package: gdb Our gdb doesn't work on PIE binaries. I don't know why you'd ever want to do this, but right now samba is linked that way. I'm just going to file a bug over there asking them to stop, but this should probably be fixed anyway. Supposedly fedora's gdb works; I haven't tried it.
Sample:
[EMAIL PROTECTED]:~$ cat hello.c
#include <stdio.h>
#include <unistd.h>
int main(void)
{
printf("Hello, fuckers!\n");
sleep(1000);
return 0;
}
[EMAIL PROTECTED]:~$ gcc -pie -o hello hello.c
[EMAIL PROTECTED]:~$ gdb hello

(gdb) b main
Breakpoint 1 at 0x612
(gdb) r
Starting program: /home/asuffield/hello
Warning:
Cannot insert breakpoint 1.
Error accessing memory address 0x612: Input/output error.
I couldn't find anything that actually worked, gdb does not appear to
understand these binaries at all. Most notably, it cannot attach to
their processes and produce a stack trace, which is proving to be
quite problematic for debugging samba.
