FWIW, my MacBook Pro gets a segfault running your test program with
DYLD_INSERT_LIBRARIES=/usr/lib/libgmalloc.dylib in the environment, too.

I'm not sure if this is a libgmalloc bug, a gcc bug, or a iostream
bug, but I just spent 20 hours boiling a crash in opencv down to
ten lines of code. Can somebody else on a MacBook Pro run the
following and see if they get a seg fault? Input from a PPC based
processor also welcome.
If this is a problem, I'm not even sure how to go back and fix the
OpenCV port, but if it's not, but at least I'll know I'm working on
a real problem.
So frustrating!
Thanks!
