[mesa-users] pointer error in mtx_support.f

[Warrick Ball]

Pablo,

Aha.  Okay, the optimization was already at -O2, so I turned it down to 
-O1.  Everything now works perfectly.  This is with:

ifort: 12.1 or 13.0
gcc: 4.4.7 or 4.7.0 (yes, I tested all four combinations)
MESA: 5271
OS: Scientific Linux 6.4 (Carbon)
