GDB Trace of execution using posix_spawn()

When attempting to debug a application in C++ that implements fork() to execute
another process through either exec* or posix_spawn* GDB fails.

132,000 ~"/home/dkg/src/gdb/gdb-7.3/gdb/thread.c:620: internal-error:
is_thread_state: Assertion `tp\' failed.\nA problem internal to GDB has been
detected,\nfurther debugging may prove unreliable.\nQu\ it this debugging
session? "

Using fork() alone executes correctly.  Only when using exec* or posix_spawn*
generates the issue.

Attempting this on the following platform

OS: Debian Squeeze (Linux 2.6.32-5-amd64)
GDB version 7.3 (Debian Backport)

I am using Eclipse CDT IDE to interact with GDB and attached is the GDB Trace.
