Debugging multithreaded program on Debian

[<alexander.schwartz@gmx.net>]

Hi,

as the subject tells I would like to debug a multithreaded programm on
debian. 

I upgraded gdb (to 4.17-4.m86k.objc.threads.hwwp.fpu.gnat.2), libc6
(2.0.7.u-4) and ddd-smotif (3.0-1) and after my program starts the
threads (pthread_create) I am unable to see these tasks (when clicking on
the proper menu in ddd). Although the task are running with no problems. 

BTW: I compile my program using g++ unsing the arguments:
  CFLAGS := -g -Wall -O3 -m486

What am I doing wrong?

Thank, Alex.
