   @pnoltes the OSX error is because pubsub_utils.c:186 tries to put 512 kb on the stack, but the default stack size on OSX is 512 kb, leading to problems. I can either reduce the stack size, use a memory allocation or increase the stack size for threads create in celix. All have their downsides:
   
   ## reduce stack size
   There is no specified maximum for topic/scope, so any reduction in stack size implicitly means that topic/scope gain a limit.
   
   ## use memory allocation
   Slow
   
   ## increase stack size
   Works for things celix controls, but as soon as someone uses the `pubsub_getEnvironmentVariableWithScopeTopic` function in a user-created thread on a system with small stack sizes, this error comes up again.
