Here we see that correct pointer is given to printf now, sans my bug.
I had a bug there (forgot to advance bbbb 4 bytes forward first).
So, this should work. Can you try this:
if (cmdedit_x >= num) {
const char *bbbb = "\b\b\b\b";
cmdedit_x -= num;
bbbb += 4;
if (num <= 4) {
bbbb -= num;
asm volatile("# HERE");
bb_error_msg("\n bbbb=%02x %02x %02x %02x (%p)", bbbb[0], bbbb[1], bbbb[2],
bbbb[3], bbbb);
printf(bbbb);
return;
}
printf("\033[%uD", num);
return;
}
Show me results of "a{backspace}", "ab{backspace}", "abc{backspace}",
"abcd{backspace}" (separate runs of hush). You may also try removing
bb_error_msg() - it might work now.
