Subject: unable to debug statically linked program with linux threads

Hi,
  I have a FC3 based i686 machine with gdb version 6.1.
  I got a simple threaded program from one BSD. (program attached)

  With dynamic linking (linux threads), I can run
  the program under gdb without a problem.
  All thread related commands seems to work properly.

  With static linking, when I run this program under
  gdb, first I get
       "Program received signal SIG32/SIG33 Real-time event 32/32".
  I avoid this problem by
        "handle SIG32/SIG33 pass nostop noprint".

  However none of the thread related command works.

  Any suggestion?

Thanks
Ajay
