Description of problem:
g77 can't compile a file (gb8414.f, you can get it from the URL) with -O (-O2
and no-optims works!)

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. g77 -c -u -g -fpic -I'/n/napa/sys' -fno-f90 -fugly-complex -fno-globals -O
gb8414.f

	

Actual Results:  well, i got an error message and no object file.

Expected Results:  i should have gotten a compiled object file.

Additional info:

the URL has it all, but here's again:

# /usr/bin/g77 -c -u -g -fpic -I'/n/napa/sys' -fno-f90 -fugly-complex
-fno-globals -O gb8414.f
gb8414.f: In subroutine `gb8414':
gb8414.f:419: Internal compiler error in fixup_var_refs_1, at function.c:1964
