One particular F90 source code file in our solver package causes gfortran to 
issue an internal compiler error and seg fault.  I have not been able to 
determine precisely what in the file triggers the problem.

I am using gfortran version 4.0.0 20050106 (experimental). It was configured 
and built for an AMD Opteron system running Fedora with no special configure 
options.  The command line for compiling the troublesome file is 

gfortran -Wall -fno-second-underscore -g -DDEBUG -c Generic_EvalsAndETAX.f90

The compiler output is

Generic_EvalsAndETAX.f90:0: internal compiler error: Segmentation fault

This is a dup of bug 16861, I found this by looking at .mod for that PR and looking for similarities (after 
seeing the backtrack was similar).

Generic_EvalsAndETAX uses generic_evalgamma and array_bounds.
generic_evalgamma uses array_bounds.

This is what makes this a dup of bug 16861.
