Yes, the actual cvs head of gdb handle the problem in a complete 
different way.
IRQ´s are runnig "behind" the step. So there is no step to the __vector. And
also if you set a breakpoint at address 0x0e the next step is a stepi 
and the following
is then the step to the next source line in irq handler. That is 
abolutly that what I want to see there!
Great, the bug is fixed :-) So lets wait until the release comes.... 
Maybe we should sometimes
test the head, I have seen bugs come back :-)

That could I not reproduce :-). Maybe you inserted the code at the wrong 
place?
There are two times the same error message in infcmd.c :-) And don´t 
forget to
recompile and maybe you should use the new compiled gdb which is without 
install under
the gdb src path? :-)))

I only tested the actual head for now. I need more then 45 minutes to 
get an "update" of the
cvs sources which is much time and so I did not test 6.2 branch. But if 
you have tested that it
should work because the same software should give same results :-)
Maybe James could do the test for the 6.2 branch. He is the originator 
of the problem
so he must have the bugfix and so he should do the test :-)


Nice to read you...

   Thanks
