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

Hello GNUstepDiscussion group,

The given below code does run in OpenStep under NT and Solaris, but is not running GNUstep/Solaris8.

The following is a simple just detaching two threads, it is giving 'Uncaught exception NSLockException, reason: Thread attempted to recursively loc"  under GNUstep

Does anybody have any clue, we  have ported applications from Open Step to GNUstep, which use plenty of threads, and often they are crashing giving stack traces in libthread.so

thanks for any help
