[vox-tech] glibc and socket()

Hi guys
I'm trying to track down a kernel bug. I've compiled my programs and the kernel
with -g, and I'm stepping through the executable with gdb.
A call to sockaddr_check() goes through OK, but a subsequent call to socket()
triggers a kernel panic. Control never even gets to the first line of socket().
Breakpoint 1, initialize_listen_socket (saP=0xbfffea78) at libhttpd.c:384
384 if ( ! sockaddr_check( saP ) )
(gdb) n
390 listen_fd = socket( saP->sa.sa_family, SOCK_STREAM, 0 );
(gdb) s
At this point, the system goes supine.
According to http://www.skyfree.org/linux/kernel_network/socket.html ,
socket() is actually a glibc function; it sets things [1] up and then calls the
system call sys_socketcall(). But I don't know where the kernel panic is
triggered, and I also don't know how to recompile glibc or even if that would
be a useful course of action.
Anyone have any ideas? I've even tried compiling the target binary with -static;
still no information on time/place of death.
Thanks
