Re: [rfa/gdb.threads] Test static thread program

Hello,

This test a static threaded program being debugged (it picks up kfails). Tested on RHEL3 amd64.

ok?
Andrew

I really really appreciate the contribution of a static thread test. I'd like to know what specific failure mode(s) you're looking for. Any chance you could test it on Solaris?
