internal compiler error

[Hans Horn]

Folks,

while playing with optimization options I ran into this one:

atamul.f: In function ‘atamul’:
atamul.f:6:0: internal compiler error: in initialize_matrix_A, at 
tree-data-ref.c:1912
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

source attached.

atamul.f

Behaves when I remove '-ftree-loop-linear'
