when compiled with xlf but i'm having an error under Linux, here the basic

Here's the error when i'm compiling:

if (   0 ) to_simex.com cts17main.f
if ( ! 0 ) /usr/bin/g77 -g -c -fdollar-ok -fno-automatic -finit-local-zero

../../../gcc/f/sta.c:510: failed assertion `!ffesta_confirmed_other_'
g77: Internal compiler error: program f771 got fatal signal 6
make: *** [main_lib.a] Error 1

Any clue of what can cause this problem?

Thanxs a lot for your help...
