I haven’t tried to get a core file yes, but it’s not producing any more info
from the runtime stack trace, despite configure with —enable-debug:

This is the configure line that was supposedly used to create the library:
./configure
--prefix=/usr/local/openmpi/3.1.1_debug/x86_64/ib/intel/11.1.080
--with-tm=/usr/local/torque --enable-mpirun-prefix-by-default --with-verbs=/usr
--with-verbs-libdir=/usr/lib64 --enable-debug
Is there any way I can confirm that the version of the openmpi library I think
I’m using really was compiled with debugging?
