One possible workaround that might be worth to try is to separate the two offending functions (RMN2L and ASWFB) in specfun.f to two different files (rmn2l.f and aswfb.f). Hopefully, g77 will compile them with -O3. If not, then at least the sizes of files are much smaller in order to find a workaround.
I have taken aswfb out of the specfun file and now the rest of the specfun.f file compiles normally. The extracted subroutine still gives the error which I will submit to the gcc bug database. It would appear that it is -O3 and -funroll-loops flags together that give the problem (any other combination of the flags does not seem to reproduce the error for me). What error are you getting on rmn21.f ? I don't see any error there. -Travis O.
