I'm working on a net burner project and I'm getting internal compiler error. Is there a way to update gcc to a more recent version?
Thanks

What error are you getting? Could you copy and paste in a build log?

This happens when the optimization level is Optimize More (-O2). When its set to Optimize (-O1) it builds just fine.

This is a "feature" of gcc when using nested swtich statements such when implementing an ASM. Please see the attached pdf. Building your own table based ASM is one way of solving the problem. This is actually not a version based problem ( from my experience ) with gcc.
