Hi,
I am using gdb 6.7.1 on a ppc embedded target (debugger and debuggee are
both running on the target as there are enough resources). The kernel is
2.6.21. Now sometimes I encounter the following misbehaviour: if I want
to single step (command step) or step over a function call (command
next), the debugger seems to execute the "cont" command instead, i.e.
the program continues until I press Ctrl-C or it stops on another
breakpoint. If it matters: the debuggee uses threads. If I start
debugging, the welcome message says:

This GDB was configured as "powerpc-603e-linux"...
Using host libthread_db library "/lib/libthread_db.so.1".
Breakpoint 1 at 0x1003383c: file cm_assert.c, line 26.
(gdb)
[the breakpoint shown is ok, it's defined in my .gdbinit file]
This happens not always, but of course every time I need the single step
mode badly. (Some AI built into gdb to needle the programmer? :-)
If I use stepi to step by machine instruction, the same happens. The
unwanted continue happens on different addresses, btw.
Any suggestions?
Regards,
Dirk
