Yikes. Thanks for the quick report, Stephen. I pushed an updated patch to get past the immediate bug and am looking more at the problem.
-- John P.S. Here are some random notes about debugging which might be useful: The log file "hs_err_pid70212.log" might have been interesting for me to look at, although it might not contain a symbolic backtrace. To get a symbolic backtrace, run java (or gamma, if that's what's built) with -XX:+ShowMessageBoxOnError. When the error crops up, type 'yes <RETURN>' to jump into gdb. Select the offending thread and say "where". (You can tell which one it is because it is waiting for input from stdin. "info threads" helps.) Also, as the error message suggests, you can try re-running with -XX:SuppressErrorAt=/ciMethod.hpp:95 to see if you get a more interesting error message. But you'd probably get a SEGV in this case.
