libepoxy 1.4.2-1 causes complete system freezes/halts

I've been getting freezes/lockups recently. I was pretty sure it was a video driver/xorg issue ,because it only happens when I'm running an OpenGL application. The whole screen would freeze, and the computer wouldn't take any keyboard input.

There are two types of freezes/lockups:
1. The whole screen is unresponsive and the computer doesn't take any keyboard inputs, but all non OpenGL applications continue to run (like a video, the audio just continues playing fine).
2. The whole screen is unresponsive and the computer doesn't take any keyboard inputs, plus it keeps repeating the last 1-2 seconds of any audio that was playing when it froze.

My logs didnt really show anything wrong, but after a quick investigation and tracking I found that libepoxy 1.4.2-1 was causing this issue. Reverting back to libepoxy 1.4.1-1 solves this issue.

Another topic that helped me somewhat: OpenGL clients hang randomly with Xorg 1.19

Running:

for n in {0..20} ; do
	x=$(((n % 5) * 202))
	y=$(((n / 5) * 152))
	glxgears -geometry 200x150+$x+$y &
done

On libepoxy 1.4.2-1 would cause more than half the clients to freeze immediately, but on libepoxy 1.4.1-1 I can make as many as I want and none of them will freeze.
