And for completeness sake, here is the corresponding 

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42616
  "OMP'ed loop inside pthread leads to crash."

Apparently this was reported against gcc 4.4.2, on "mingw32 on Windows XP" (so it is not just Mac OS X affected), "Last modified: 2010-01-22". And it is apparently not yet fixed.

Maybe this issue /did/ work (apparently on my Ubuntu 8.10 with gcc 4.3.2), but now broke (again)? To be continued... :)


Cheers, Oliver
