Re: [hatari-devel] logging segfault (was: another one I have since a long time)

[Laurent Sallafranque <laurent.sallafranque@xxxxxxx>]

Hi Eero,

Yes, I can still reproduce the bug.
Here are my files, attached to this mail.

I run hatari just by doing ./hatari   (no extra commands)
I wait until hatari reach the Falcon desktop.

Then, I open the GUI and I change :
In System, I change:
   - Machine type :  ST
   - Video timing : no change
   - Falcon DSP : None
   - Blitter, Patch timer-D and boot faster are left unchanged (and not 
checked)

In CPU, I change:
   - CPU type : 68000
   - CPU Clock : 8 Mhz
   - FPU : None
   in CPU emulation parameters, I only uncheck MMU emulation, I leave 
the other parameters checked

In ROM, I select the TOS 1.04 fr
In memory, I just change the memory setup to 512 kb

And that's all. I don't save the changes, I just click on Reset Machine 
and I get the "Core dump"

If I do the same (ie start from falcon mode, apply all the changes, but 
save the conf to hatari.cfg and then click to reset, I get the core 
dump, but when I restart hatari (./hatari), it starts well in ST mode.

The core dumps appears only when I want to switch from falcon to ST mode 
"on the fly".

To be noticed: if I start in STf mode and try to switch to falcon mode 
on the fly, it runs well.


I've attached my hatari.conf file and my French 1.04 TOS (in case of).


Don't hesitate to ask for more tests or file if needed.

Regards
Laurent
