Summary: compile-time core dump building input_head.f from
LS3DF
Product: flang
Version: trunk
Hardware: Macintosh
OS: Linux
Status: NEW
Severity: normal
Priority: P

LS3DF source code that causes f18 to core dump.
The source file is from a DOE science code:
flang -O2 -Mfixed -c input_head.f
f18 core dumps during the compile phase. When I run gdb on the core, this is
what I see:
Core was generated by
`/scratch/naromero/opt/spack/linux-ubuntu18.04-westmere/gcc-7.4.0/f18-master-lom'.
Program terminated with signal SIGSEGV, Segmentation fault.
