RSC-C (Browser) Freezes Computer on ChromeOS

[M00NB0LT]

I'm not sure how much useful l information I can provide, but RSC-C on Chrome appears to cause my Chromebook to freeze up, black-screen and crash after playing for a short period of time.

I noticed it happening a month or two back but attributed it to faulty hardware, but I took a break from playing for awhile and didn't have any crashes on said Chromebook until I used RSC-C again.

If you know of any ways to provide useful info, let me know. I don't receive any error reports or anything after it happens.

Using windows it does that too after a few minutes, the exception appears here leading to a crash:

I wonder if anyone else has this problem, the pointer scene->scanlines is being overwritten and pointing to garbage causing a segment fault in the above location. A memory breakpoint shows it's happening here (I have no idea why):

edit: i found the problem here
it should be:
int gradient_index = ((float)rand() / (float)RAND_MAX) * (RAMP_COUNT-1);
otherwise it will overwrite loads of variables including scene->scanlines
