Could you please provide more detail on how your test case fails and what is different about the generated code.

Not that I'm aware of.

I pushed one change yesterday that fixed an issue with Catch_StackOverflowError_01. It triggered when C2 compiled code threw an exception that unwound to Graal compiled code. The (new) exception handler stub in Graal asserts that the exception PC stored in the current thread is 0 and this assertion was failing.
