[MC-26793] Random crashes in demo

Random crashes, haven't established a pattern. Rebooted, loaded Windows updates, no change. Playing in full-screen mode. I'm a Java developer, can do diagnostics if required.

Just started couple days ago, trying demo. Nice game. Thanks,

Duplicate of MC-12949.
Assign more memory to Minecraft.

Based on a crash report provided in this issue, I believe with high certainty that this report may be a duplicate of MC-16803. You can view all information known about this specific crash at MCX-609.

BTW: Download the 1.6.2 demo: https://minecraft.net/download

Just documenting general confusion:
1) The demo web pages are explicit that the download is for those who have made a purchase. But after doing the download I see that it does indeed offer the 1.6.2 demo.
2) MC-12949 refers to http://hopper.minecraft.net/help/out-of-memory/ which says for 32bit we need to reduce memory, but it doesn't go any further. I have 8GB RAM and can only guess at what value <1GB that I should try. Understanding the issue now I see my crash report shows my memory usage at -Xmx1g. Might this issue be fixed for me with -Xmx2g or is JRE32 still only using a max of 1GB?
3) I run the v1.5.2 demo on a different Win7/32bit with no issues. The problem here seems unique to JRE32 over Win/64/WoW32. I'll install JRE64. Running in the 32bit browser will probably not change anything so I'll run with the downloaded launcher and JRE64 and see how that goes. Thanks for that tip.
