[mvapich-discuss] segmentation fault (signal 11), Exit code 139Ok

[Ed Wahl]

>From one of my pbs batch scripts.  Seems to work for me (but then I cannot get 1.7+ to give me a real stack dump, but backtraces are working fine):

export MV2_DEBUG_SHOW_BACKTRACE=1 

for the dumps to work right (when they dump):
export MV2_DEBUG_CORESIZE=unlimited

Ok, so I recompiled with the debug flags but didn't get any additional error
info. Where do I look for the info? How do I invoke
MV2_DEBUG_SHOW_BACKTRACE?

Can you tell us a little bit about the architecture of systems as well
as the software environment (such as OS and any schedulers in use).

I also suggest taking a look at
https://mvapich.cse.ohio-state.edu/support/user_guide_mvapich2-1.8.html#x1-1
120009.1.10

Try using the MV2_DEBUG_SHOW_BACKTRACE parameter to see if you get more
output.  Also when doing your debug build, use --disable-fast in
addition to --enable-g=dbg.
