[Bug optimization/13202] New: ICE in tree-dfa.c for Fortran source code

[schnetter at aei dot mpg dot de]

I receive the error 
 
/home/eschnett/Calpha/Cactus/configs/einstein-gfortran/build/ADM/DoubleLeap.f: 
In function `adm_doubleleap': 
 
/home/eschnett/Calpha/Cactus/configs/einstein-gfortran/build/ADM/
DoubleLeap.f:0: internal compiler error: in add_may_alias, at tree-dfa.c:2002 
Please submit a full bug report, 
with preprocessed source if appropriate. 
See <URL:http://gcc.gnu.org/bugs.html> for instructions. 
 
when compiling the attached file with the options 
 
/home/eschnett/gcc-3.5-tree-ssa/bin/gfortran -march=pentium3 -malign-double 
-m128bit-long-double -x f95 -g -O3 -funroll-loops -c -o $current_wd/
DoubleLeap.F.o $current_wd/DoubleLeap.f 
 
 
 
The error does not occur when I compile without optimisations. 
 
The failing source file uses the module ADM_Scalars.  I include the source for 
that module as well. 
 
My gfortran version is 
 
$ ~/gcc-3.5-tree-ssa/bin/gfortran -v
