The (shortened) fortran-77 subroutine attached below causes a

$ g77 -O3 -c -funroll-loops foo.f

No problems occur without optimization.
$ g77 --version

Let me know if you need to know anything else.

G77 is no longer maintained. The new fortran compiler is gfortran and it supports f77 code. I will test to see if gfortran handles your test case.

Also, please correspond with the gfortran list on this so we fortraners can help you here. There are gfortran binaries available. Let me know if you need help with this. Also helps to know what hardware platform you are on and what OS you are using.

Regards,

Jerry
