-O compiling mixed language code seg faults

[Robert Williams]

System: egcs-980122, axp/RedHat-5.0, 2.1.82 kernel

A main Fortran program that calls a C language subroutine
(via an archive library...C code calls assembler routine in same
library)
seg-faults when compiled with the -O option.
It works fine when compiled with -g , or with -g -O2 (or O3).
Working executables are produced with any -On link option.
Looks like a bug.
