Indeed, for mips-elf/gcc/cc1 -fpreprocessed 991019-1.i -quiet -dumpbase 991019-1.c -O0 -O3 -w -version -o 991019-1.s I see:
GNU C version 3.2 20020723 (experimental) (mips-elf)
        compiled by GNU C version 2.96 20000731 (Red Hat Linux 7.1 2.96-98).
/export/home/build/srcw/gcc/testsuite/gcc.c-torture/execute/991019-1.c: In function `main':
/export/home/build/srcw/gcc/testsuite/gcc.c-torture/execute/991019-1.c:28: internal compiler error: Internal compiler error in int_mode_for_mode, at stor-layout.c:292


int_mode_for_mode aborts when you pass it a MODE_CC mode.

	* simpify-rtx.c (simplify_subreg): Don't pass MODE_CC mode to
	int_mode_for_mode.
