Re: Fw: Code excerpt, running in OpenStep and failing in GNUstep!

Stephen,

thanks for responding

We found out the problem, it seems the GNUstep is doing some extra exception
handling for locks.

Here i was locking twice in main method, twice to lockthe main thread, so
that child threads can do their job. Such a thing was ok for OPenstep, but
GNUstep was throwing exception may be to warn a deadlock

thanks

Ramana Rao
