gdbserver 6.0 (ppc) core dump on continue from gdb 6.0(x86), but not with debug_thread=1

[Albert Ho]

More info on a question asked previously at 
http://sources.redhat.com/ml/gdb/2004-02/msg00301.html

The test program involves pthread. The libpthread.so.0 is loaded 
correctly on both host and target.

With debug_thread set to 1 in gdbserver/linux-low.c, a test program on 
target ppc with 5 threads can be controlled from gdb on x86 host. With 
the same setup, a bigger program still got SIGTRAP on pthread_create 
(the real thing has 4 threads).

With debug_thread set to 0, the test program get a SIGTRAP on 
pthread_create().

Any advice on how to debug from there?


Thanks
