JVM 24.95 SIGSEGV on C2 Compiler Thread

[Gustavo Romero]

Hi Martin,

I'm facing a problem with a JVM 24.95 when running an application.
However it's being hard to reproduce it, ie many times C2 will
optimize the method fine and the application terminates fine. Just
after many complete runs, one of them will crash. Apparently it is
related to https://bugs.openjdk.java.net/browse/JDK-7068051 bug,
but it was fixed in hs22 and as I could not isolate it on PPC64,
I can't tell if it still exists upstream on PPC64.

Do you have any clue on how to isolate/debug this problem?

Backtrace from the thread that caused the segfault:

Thank you!

Best regards,
