Whenever I try to run these builds, I get the generic "This program has stopped working" error. The April 1 builds work fine, as do any that I build myself (even those based on this revision).
In case it's useful, here's the full debug log that's generated when no command-line arguments are passed (yes, it does stop immediately after the warble_fs2 line):
