pthreads & gdb: zombie threads?

Hello,

I'm having a strange problem debugging a pthreads application in 2.2.18 (as per SuSE 7.1):

gdb says the program terminated normally after having started two or three LWPs. I can exit gdb then, and I find (ps -ax) one zombie thread and two or three other threads. Is it more likely a kernel problem, a library problem, or a gdb problem?

Naively I thought when exiting the process, all threads would die...
