Internal compiler error in g77 3.2

["Kevin B. McCarty" <kmccarty at Princeton dot EDU>]

Package: g77-3.2
Version: 3.2.2-0pre3

The original source code file muller.F (which triggers an internal
compiler error), preprocessed file muller.f, and assembly file muller.s
are attached to this email.  The compiler error occurs only on 
optimization of -O2 or higher.

Output of gcc -v:
