 Hi,
 
 the bug seems to be fixed since both testcases (the original one and the
 reduced one) now compile fine with gcc 3.1.1 20020701 and gcc 3.2
 20020702 (checked on i686-pc-linux-gnu).
 
 Hence, the PR can probably be closed.
 
 Greetings,

 Hi,
 
 the testcase can be reduced to the following code snippet
 (which even fails with "gcc -O -c"):
 
 ------------------------------snip here--------------------------
 float foo (void)
 {
     float x[2];
     return x[1];
 }
 ------------------------------snip here--------------------------
 
 The bug is a regression from 3.0.x and is present in 3.1 and the main
 trunk (gcc 3.2 20020609) - checked on a i686-pc-linux-gnu.

>Description:
I am trying to run the test after compiling the latest CVS version of GNU Scientific Library, but the compiler aborts. Asked GSL mailing list for support but the consensus was that this error should be reported to gcc development team.

A plain 'configure' was used when gcc was compiled.

Compilation command:
/usr/local/bin/gcc -DHAVE_CONFIG_H -I. -I. -O2 -c test.c
gives the below respons. Compilation is ok if optimization is turned off (-O0).

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
Please submit a full bug report,
with preprocessed source if appropriate.
