>From my man pthread_cleanup_push:

Matching  pairs of !pthread_cleanup_push! and !pthread_cleanup_pop!
must occur in the same function, at the same level of  block  nest‐
ing.   Actually,  !pthread_cleanup_push!  and !pthread_cleanup_pop!
are macros, and the expansion of !pthread_cleanup_push!  introduces
an open brace !{!  with the matching closing brace !}! being intro‐
duced by the expansion of the matching !pthread_cleanup_pop!.

SO if this is a bug .. it is shared by Linux..:)
