Any ideas on how to debug this further locally? If I add,,,

or

       LINE(2:2)='|'
       LINE(80:80)='|'

the problem is suppressed. The issue is also suppressed with,,,

-O0
-O1
-O2/-O3 -funroll-loops
-O2/-O3 -funroll-all-loops
-O2/-O3 -fno-PIC

I've tried about every other option and those don't suppress the problem.
