ICE, posibly related to bug #30667

[Ignacio Fernández Galván]

Hi all,

I found a compiler error with this simple test case:

      subroutine gaussj2_cvb(n)
      dimension irows(n)
      do 100 i=1,n
100   irows(i)=i
      end

With gfortran 4.3.0 20070209 (linux), on an Athlon-XP, this fails:

$ gfortran -c -O1 -march=athlon-xp -ftree-vectorize test.f
test.f: In function ‘gaussj2_cvb’:
test.f:3: internal compiler error: in expand_simple_binop, at
optabs.c:1192
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

Leaving out any of the -O1 -march=athlon-xp -ftree-vectorize options
makes it work,though.
