hires textures causing crashes

[kody]

I'm attempting to rename and use some textures from Zelda ocarina of time texture packs for use with the master quest gamecube version (im aware that it is only an emulation of the n64 version), because dolphin's graphics plugin supports a widescreen hack and hires texture loading at the same time. Everything runs fine I tested it every few minutes just to see the new textures ingame but now it crashes after about 30 seconds of running around ingame but only when the hires texture option is on. Is this a know bug? I tested on several of the newer builds (6095 and 6200 and a few between)
