You need to backtrace f951 (which is the compiler proper) instead of gfortran
(which is only the driver). Use "gfortran -v" instead of "gfortran" in your
normal compile command, and it will tell you what options f951 is invoked with
(there usually are a lot of those). Then, run this f951 command-line under gdb,
and you will have backtrace. If the ICE is not due to a segfault, but rather to
a failed GCC assertion in the source, you might want to set a breakpoint on
fancy_abort and get a backtrace when this function is called.
