  * status:  new => patch


Comment:

 the above patch uses mmap to allocate the section on OS X and fixes the
 crash here. It will likely still crash if there are multiple huge global
 arrays like in the example by nus (that exhaust the lower 2GB of mem), but
 that scenario is probably not exactly common.

 It works on my system with Mountain Lion (10.8), i can't test with older
 systems unfortunately.
