debugging threads

[Pierre Abbat]

This is the same program as in my previous email. It has a main thread which 
starts two threads. I run gdb on it. On caracal it says:

(gdb) break initnetwork
Breakpoint 1 at 0x429950: file /home/phma/src/ampelos/network.cpp, line 25.
(gdb) run

Breakpoint 1, initnetwork () at /home/phma/src/ampelos/network.cpp:25
25      {

On darner it says:

(gdb) break initnetwork
Breakpoint 1 at 0x80536e5: file /home/phma/crypt/ampelos/network.cpp, line 27.
(gdb) run

Program received signal SIGTRAP, Trace/breakpoint trap.
0x282dbe3b in nanosleep () from /usr/lib/libc.so.7

Trying to switch threads in DFly doesn't work. Is this a bug in gdb, or what? 
Where should I report it?
