Your gcc -v information?
And your cpu model? (I think it's related with cpu instruction set)
I use i686-w64-mingw32 gfortran 4.6.2 to run the test well on Win7 intel core2.

The issue is related with "-mavx"
I use "gfortran -O3 -mavx" to reproduce the problem.

Excellent, just for completeness, I can confirm that :
gfortran -O3 -mavx
does reproduce the problem identically and that :

Excellent, just for completeness, I can confirm that on my machines :
gfortran -O3 -mavx
does reproduce the problem identically and that :
gfortran -O3 -mno-avx -march=native
compiles successfully.
