Linux x86_64 application aborts with segmentation violation

Hi all,

I rejoined today, and found the executable of "Gravitational Wave All-sky search on LIGO O1 Open Data 0.02" failed to run on my Fedora 29 rig.  It says:

putenv 'LAL_DEBUG_LEVEL=3'
SIGSEGV: segmentation violation

So I run as "LAL_DEBUG_LEVEL=3 ./ein*gnu" on bash shell, then it aborts with "Segmentation fault (core dumped)".   What can I do?

This rig uses glibc-2.28 and gcc-8.2.1.

Thanks in advance!
