Re: [MC++] Internal Compiler Error with /Ox

they mention that value types cannot contain pointers to other managed
types. In my __value struct, I had an array of other __value objects,
so I changed it to an unmanaged array. Now, when I compile using /Ox
for full optimization, I get an Internal Compiler Error.

It turns out that any of the optimization switches I tried resulted in
the ICE.

Can anybody propose a workaround? Upgrading to VS 2005 is not an option
at the time.

bool is_blank(const Contours& contours)
{
Contours::ContourInfo empty = {0, 0, 0, 0};
bool blank = true;
for (int i = 0; i < contours.num_contours; ++i) {
if (!__box(contours.contours[i])->Equals(__box(empty))) {
blank = false;
}
}

return blank;
}

I changed this to

bool is_blank(const Contours& contours)
{
bool blank = true;
for (int i = 0; i < contours.num_contours; ++i) {
if ((contours.contours[i].lower_bound != 0.0) ||
(contours.contours[i].r != 0) ||
(contours.contours[i].g != 0) ||
(contours.contours[i].b != 0)) {
blank = false;
}
}

return blank;
}

and I no longer get the ICE.
