[Bug fortran/35892] New: gfortran dies on file containing module and common

["KnowlesPJ at Cardiff dot ac dot uk" <gcc-bugzilla@gcc.gnu.org>]

Compilation with -O0 -g causes the compiler to crash:

/opt/gcc/bin/gfortran -c -fno-second-underscore -fdefault-integer-8 -m64 -g -O0
--save-temps f12_integrals.f
f12_integrals.f: In function 'f12_integrals_raw':
f12_integrals.f:980: internal compiler error: in expand_expr_real_1, at
expr.c:7258
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Using built-in specs.
Target: i386-apple-darwin9.2.2
Configured with: ../configure --prefix=/opt/gcc --enable-languages=c,fortran :
(reconfigured) ../configure --prefix=/opt/gcc --enable-languages=c,fortran
--no-create --no-recursion
Thread model: posix
gcc version 4.4.0 20080409 (experimental) (GCC) 

Although gcc -v reports 'i386' this is in fact an x86_64. But compiling on a
true ia32 (and omitting -m64) produces the same crash.

With -g removed or -O1 the compiler completes. However we are getting wrong
results, so perhaps the place to start is with the crash and then try again?
