Thread model: single
>Description:
When compiling the file test.c (from the GNU Scientific Library v1.1.1) with the optimization level 2 or 3, an internal compiler error occurs:

In file included from test.c:61:
test_complex_source.c: In function 'test_complex_float_trap':
test_complex_source.c:258: Internal compiler error in subst, at combine.c:3546
>How-To-Repeat:
The command line is:

gcc -DHAVE_CONFIG_H -I. -O2 -c test.c
>Fix:
With -O0 or -O1, the ICE does not occur.
