[M3devel] OpenBSD/x86 pthreads

[Tony Hosking]

This looks odd -- the assertion should not fail.  It is reporting that  
recorded stack base is not is not in range of the reported stack  
info.  What exactly does OpenBSD report in the sinfo?  Which thread is  
this?  I need a full stack trace of all the threads to understand what  
is going on here.
