[mvapich-discuss] mpirun Segmentation fault

[Jonathan Perkins]

Which version of MVAPICH2 are you using (mpiname -a)?

You can try getting the backtrace from the generated core file (should
be named core.9999 where 9999 is replaced with some number).  If you
find this you can do something like "gdb mpirun core.9999" and then
type in the command "thread apply all bt" at the prompt.
