[Bug c/39928] New: gimplify_expr failure

[dcb314 at hotmail dot com]

I just tried to compile the Suse Linux package speex-1.1.99.91-15.19
with the GNU gcc version 4.5 snapshot 20090423.

The compiler said

vq_sse.h: In function 'vq_nbest':                                      
vq_sse.h:52: internal compiler error: in gimplify_expr, at gimplify.c:7175     
                                                                Please submit a
full bug report,
with preprocessed source if appropriate.                                See
<http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. No special flags required.
