Texture glitching when using more than 1G of RAM

*1.9 WAS NOT IN AFFFECTED VERSION/S SO I PUT ALL OF THEM. THIS BUG AFFECTS VERSION 1.9+*When trying to start a world with 1G of ram, the game crashes into a "Cannot create main dump". The crash log is In the attachments. This crash also only happens in 1.9+ When I set the usable ram to more than 1G, I can go into worlds but the textures are broken. The GUI is fine, as are particles and chat. See screenshots for more. I have tried a reinstall of Minecraft, java, and a graphics driver update and that has changed nothing.
