Hi Peter,
as I see, TThread::fClean is not nullified in any TThread ctr.
Probably you do not use ROOT NewDelete who is doing it
Anyway, of course it must be preset to zero in ctr. It is my fault.

Fons, could you add it into TThread.cxx

I've been trying to resolve a segmentation violation in a standalone thread 
application (Intel/Linux 7.1/Root 3.00/06).  It blows up in TPosixThreadCleanUp:
:TPosixThreadCleanUp apparently going through a chain of cleanup routines. 
 Line 126 attempts to call 'main'  which is an argument passed in by
  TPosixThread::CleanUpPush, which is apparently set from fClean.  
  However, in searching the source, I can not see anywhere that fClean is getting set
  , not in any of the constructors nor in Thread::Constructor. 
   The value being passed by TPosixThread::CleanUpPush fro mainis 0x4
    (which certainly can explain the segmentation violation). 
    Was I supposed to explicitly set a clean up routine?

BTW - root running the CalcPi demo also gets a segmentation violation as well, but that's a little more difficult to track with gdb,
so I assume it's the same problem.

Any help would be appreciated.

Thank you,
Peter Gallanis
