GDB 4.18 doesn't include LinuxThreads support, so the signals the
threads use to communicate with each other confuse GDB. Because GDB
doesn't know what the signal is, you can't really tell it to pass it
through.
Try a GDB snapshot from http://sourceware.cygnus.com/gdb. The
LinuxThreads support is in there.
