It actually renders it unusable if the ram size is bigger than that in the device you are using as the stack top will be set outside the available ram. It has only ever worked before with the correct ram/flash sizes as I pointed out to you. It should be for specific known combinations, the ct_stellaris was incorrect before you diff'ed it, and now you have introduced another error (stack_top=0x20fffc?). Personally, as somebody using this compiler on real projects, I think there are too many changes proposed here in one hit, completely untested. festina lente
