My problems on 10-STABLE seem to happen at random, as if it were bad RAM. In successive builds of the 'pkg' port, for example, I get different results each time: a segmentation fault during 'configure', then no errors, then a syntax error in some file, then a segmentation fault during 'cc' of something small, then no errors. I didn't see any such weirdness before the native build, though. How can I diagnose this further?
