After a second thought, that there were probably not many people using the ‘enable-multiple-vms’ option, so I decided to take some time to track it down.
The OS X linker does not support linking an "extern __thread var”, I can do nothing about that. But the crash bug in pthread_get/setspecific fallback approach, turned out to be a minor issue: the pthread_key_t has to be created before used.
Patch follows, but i am not sure that is the right position to fix it.
