this reminds me of a problem with vfork that I encountered some years ago. The 
problem as described in 
http://sourceware.org/ml/libc-alpha/2003-02/msg00042.html
was fixed for many architectures, but not for hppa as far as I remember. See 
also 
http://sourceware.org/ml/libc-hacker/2003-02/msg00015.html

I have no idea if this is related, but thought it won't hurt to mention this.

Berthold
