Here is another test with confirmatory data.
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:

zdenek patch is the version from
