==21333== Your program just tried to execute an instruction that Valgrind
==21333== did not recognise. There are two possible reasons for this.
==21333== 1. Your program has a bug and erroneously jumped to a non-code
==21333== location. If you are running Memcheck and you just saw a
==21333== warning about a bad jump, it's probably your program's fault.
==21333== 2. The instruction is legitimate but Valgrind doesn't handle it,
==21333== i.e. it's Valgrind's fault. If you think this is the case or
==21333== you are not sure, please let us know and we'll try to fix it.
==21333== Either way, Valgrind will now raise a SIGILL signal which will
==21333== probably kill your program.

To: ruby developers list
Issue #8624 has been updated by nobu (Nobuyoshi Nakada).
手元のx86_64-linux環境では、illegal hardware instructionも再現せず、
valgrindも何も出さなず、x86_64-darwnでもvalgrindのエラーは出たものの
illegal hardware instructionは再現せず、でした。
とりあえず、valgrindのエラーは出なくなったと思いますが、まだ落ちるよう
ならreopenしてください。

==21333== Your program just tried to execute an instruction that Valgrind
==21333== did not recognise. There are two possible reasons for this.
==21333== 1. Your program has a bug and erroneously jumped to a non-code
==21333== location. If you are running Memcheck and you just saw a
==21333== warning about a bad jump, it's probably your program's fault.
==21333== 2. The instruction is legitimate but Valgrind doesn't handle it,
==21333== i.e. it's Valgrind's fault. If you think this is the case or
==21333== you are not sure, please let us know and we'll try to fix it.
==21333== Either way, Valgrind will now raise a SIGILL signal which will
==21333== probably kill your program.
