Try perl t/harness --core-tests and see what tests fail. (Obviously, ones that depend on PGE will fail, but we already know that. You're looking for simpler test cases.) Then, once you find tests that fail, try running those individual tests with parrot (and also with parrot -G to turn off garbage collection) and see what's the smallest or simplest failing test case you can find. They might be better candidates for debugging. -- Andy Dougherty [EMAIL PROTECTED]
