pthreads debug with gdbserver

[Vladimir Vorobyov <vladimir dot vorobyov at iss dot org dot ua>]

Hi,

Im using gbd 6.2 + gdbserver for m68k target and able to debug programs with 
it. But when I tried to debug application with pthreads I could not get 
correct threads information.
During debbuging I receive a well known SIG32 but searching this mail list I 
did not find the solution for my problem.
What I did:

        breakpoint already hit 3 times
***************************************************************************************************
I see that shlib breakpoint is set and hit but gdb does not load the 
libraries. I can see in strace that it successfully loads ld.so. What should 
I look at?
Next, what libthread_db.so is for? It was not included for compilation for 
m68k target and I added it manually but when I try to load all libraries 
manually using add-symbol-file, every library loads fine except 
libthread_db.so - gdbserver reports "gbd: error initializing thread_db 
library."
If I type in gdb:
	info threads
I always get only one thread.
p.s. All libraries are not stripped.


Any help would be very appreciated.
