--- Comment #24 from William Bader <williambader at hotmail dot com> ---
Jakub was right. I didn't understand what he meant at first. Sorry about that.
I can confirm `gcc -m32 -O9 -fexcess-precision=standard gcc-bug1-init.c` on the
original example works correctly for me.
If I change line 758 (the line after #if BUG_FIX) from
if (new_qxd4_y == cur_qxd4_y && new_qxd4_x > cur_qxd4_x) {
to
if (new_qxd4_y >= cur_qxd4_y - 0.001 && new_qxd4_y <= cur_qxd4_y + 0.001 &&
new_qxd4_x > cur_qxd4_x) {
then it also works.
Years ago I did scientific programming in fortran, and I should have remembered
from that never to compare two real numbers for equality.
