Charm++ parallel programming system

[Tom Quinn <trq AT astro.washington.edu>]

I'm running an ibverbs standalone for debugging, but I don't get very far 
because of a segfault.  valgrind reports the following.

Line 2529 of machine-ibverbs.c has a simple

 if (Cmi_charmrun_fd == -1) return malloc(size);

whereas infi_CmiFree() assumes the pointer has been advanced to allow for 
the header.
