--- Comment #2 from David Binderman ---
I get the same for this C++ code:
struct {
long length();
} fromBase32Hex_input;
int set_bits_start, set_bits_length;
char fromBase32Hex_block[1];
char fromBase32Hex_cr;
void fromBase32Hex() {
for (; fromBase32Hex_input.length();) {
char *s = fromBase32Hex_block;
char cc = set_bits_length >> 8;
if (set_bits_length) {
s[set_bits_start / 8] |= cc;
s[set_bits_start / 8 + 1] |= fromBase32Hex_cr;
}
s[set_bits_start / 8] |= fromBase32Hex_cr;
}
}
