[mpich-discuss] mpich2-1.2.1p1 and Intel 11 Compiler

[chan at mcs.anl.gov]

Can you build mpich2-1.2.1p1 without --with-device=ch3:shm
and see if it works with your app ?  If the segfaults still
occur, could you send us either 1) a simple program that reproduces
the problem or 2) a backtrace that shows where segfault occurs.
