Hello,
I am having the exact same issue: crash while in full screen and loading JPEG images under Windows 7 64bits.
I tried loading a lot of different JPEG images from different sources and different size (very small to very big) and the issue keeps happening. I have no issue when loading GIF, PNG or TGA images.
I also tried to use JRE 32 bits instead of 64 bits and it doesn't change anything.
I also confirm that the issue is not happening if the image is loaded during the init() method.
I'm using Slick Build #274 and LWJGL verion 2.7.1.
It's true that we don't get any error message but we do get an exit code other than 0. It's never the same exit code but it is always very big and negative like for example "-1073741819" or "-805306369".
I tried to run the code from appel and I get the error as you can see:

I will make some additionnal tests on my side (under Windows Vista 32 bits for example) and give you as much information as possible.
Thx
