GDB stops working with 2.6.9-1.724_FC3smp kernel (threads, IntelMKL)

["Adrian Broadhurst" <adrian_broadhurst hotmail com>]

I have just installed the new kernel 2.6.9-1.724_FC3smp (previously 
1.667smp) and now gdb cannot find the child process when you type run.  This 
program uses Intel Math Kernel Library, which uses pthreads and guide.  
Tested on 2 different machines, with 2 independent executables.

I suspect this is a threads issue.  Has anyone else had this problem?
