[mvapich-discuss] mvapich2-0.9.5 and gdb

[wei huang]

Hi,

THanks for the information.

We did test on gdb when releasing mvapich2-0.9.5 but we did not see any
problem as you described. Is a.out a very simple problem like cpi? Or can
you please run this command with cpi program (in mvapich2/examples) and
let us know how it comes out?

Thanks.
