Subject: [OMPI devel] One-line patch for warning in 1.7rc6
From: Paul Hargrove (phhargrove_at_[hidden])
Date: 2013-01-25 21:16:51


While building 1.7rc6 on a i386 w/ InfiniBand I saw numerous instances of
this warning:
   ../../../../../orte/mca/oob/ud/oob_ud.h:93: warning: cast from pointer
to integer of different size

The following 1-line change fixes this.
Alternatively, a single cast to type uintptr_t is probably sufficient.
