I've installed the patch in the meantime, so feel free to update it with the N64 variants you see on IRIX != 6.5.30 (might even vary in patches, though). >> 64-bit stack_check2.adb remains broken, though.

They were, but libjava on both IRIX and Tru64 UNIX didn't make use of MD_FALLBACK_FRAME_STATE_FOR yet. I've just fixed that, which allowed me to get rid of another testsuite failure there. Thanks.
