Problem with GDB and threads

On a RH 7.2 s/390 system I'm trying to track down a squid problem I'm
having.  When squid cores all I get from the backtrace is

#0  0x4025f9de in kill () at soinit.c:56
#1  0x4016f360 in raise (sig=6) at signals.c:65
#2  0x40261124 in abort () at ../sysdeps/generic/abort.c:88
#3  0x004967e2 in strcpy () at soinit.c:56

This is incomplete.  I don't know, but I think it may have something to
do with these messages:

Reading symbols from /lib/libpthread.so.0...done.

warning: Unable to set global thread event mask: generic error
[New Thread 1024 (LWP 16999)]
Error while reading shared library symbols:
Cannot enable thread event reporting for Thread 1024 (LWP 16999):
generic error

glibc-2.2.4-32
gdb-5.1-1

Any ideas?
