  hmmm I see. hmmm isn't there _any_ chance that you can have access to
a linux box to see if that fails in the same conditions ? I mean I
believe qemu (or virtual pc or …) on your macos would be just fine.

  But this realloc() that returns 0xd looks fishy. I would be tempted to
think of a stack corruption, but the frame just before still looks
correct so I'm confused. And valgrind is definitely the tool to use for
stack smashing and other memory related corruptions :/

  Using gcc -Wstack-protector may also help.
