Command line: gcc -msse2 -O main.c
(1) The generated executable causes segmentation fault while running. It looks
like some alignment problem.
(2) If test1 and test2 are called directly from main(), not through test3, the
problem disappears.
(3) If the line "t2 = coeffs" in test1 is commented out, ICE happens:
main.c: In function `test1':
main.c:33: internal compiler error: in immed_double_const, at emit-rtl.c:481
