gfortran -O3 -ftree-loop-linear -ftree-vectorize air.f90
gives:
air.f90: In function 'MAIN__':
air.f90:28: internal compiler error: Segmentation fault
Using -O2 or dropping one of the -f options removes the error. Occurs also with
-m32. This is with today's GCC 4.3 (r124742). It was working with yesterday's
2007-05-14-r124708 on x86_64-unknown-linux-gnu.
Test case is part of
