figuring out what happenend within the java.lang.Thread.<init>

[Peter Helfer]

Ok, I'm running again into troubles..

This is what I'm seeing:

VM option '+UnlockDiagnosticVMOptions'
VM option '-VerifyBeforeExit'
PARENT[80D8800]: getThread: Linked threads 80D8800 <--> 80DA800

Now how can I track or figure out, what has happend within
java.lang.Thread.<init>
? - this is just the normal stack trace output, are there any other means ?
When using GDB (thx Tom for the script!), I can only see backtraces, which
end up in os::raise(), but I'm having issues to set breakpoints, even when
using "sharedlibrary libjvm"...
