# we turn off the test for MRI 1.8 because our source_location hack
# for C methods actually runs the methods - and since it runs ALL
# methods (in an attempt to find a match) it runs 'exit' and aborts
# the test, causing a failure. We should fix this in the future by
# blacklisting certain methods for 1.8 MRI (such as exit, fork, and so on)
