Test case, reduced from some firefox code: int punycode_decode(const char input[], unsigned char case_flags[]) { int j; for (j = 0; j < 128; ++j) { if (case_flags) case_flags[j] = input[j] - 65 < 26; if (input[j] < 32) return -1; } return 0; } With native i686-pc-linux-gnu, my results are: gcc 4.0.1, command line "gcc -S -O3 z1.i", no error gcc 4.1-20050819 snapshot, command line "gcc -S -O3 z1.i", ICE: z1.i: In function 'punycode_decode': z1.i:2: internal compiler error: in finalize_ssa_uses, at tree-ssa-operands.c:580 gcc 4.1-20050902 snapshot, command line "gcc -S -O3 z1.i", ICE: z1.i: In function 'punycode_decode': z1.i:2: internal compiler error: in finalize_ssa_uses, at tree-ssa-operands.c:580 gcc 4.1-20050902 snapshot, command line "gcc -S -O3 -fno-ivopts z1.i", no error gcc 4.1-20050902 snapshot + zdenek patch, command line "gcc -S -O3 z1.i", no error zdenek patch is the version from http://gcc.gnu.org/ml/gcc-patches/2005-08/msg01647.html . -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23509
