I have gcc 4.5.1 20100506 on x86_64-apple-darwin10.3.0, and it compiles fine.
The Fortran patches between my version and yours are:

        GFC_POINTER_TYPE_P.
------------------


None of these look like they could be "it". It could be something outside the
Fortran front-end, or a 32/64-bit issue (but then, we'd probably see it on
32-bit linux too).

If you have time, can you:

  1. Using "gfortran -v", isolate the invocation of the compiler itself, f951
  2. Copy-paste this command-line and run it under gdb: "gdb -args [command
line here]"
  3. When it aborts, backtrace (command "bt") and copy-paste the output of gdb.

This will give information on where to look.
