program crash xdosemu

[trebosc]

Hi, 

I'm trying to run a program under dosemu 1.2.0 with freedos
The program uses a TSR program (HSGR from PC Soft) for graphic 
visuals.
Except for graphics, the program runs 
fine (don't crash) in xterm console (dosemu) with the standard configuration.

When run with xdosemu, I get the graphical splash screen then 
dosemu crashes with the following error :
ERROR: Fault in dosemu code, in_dpmi=1
ERROR: BUG: dosemu touched the protected video memory!!!
ERROR: cpu exception in dosemu code outside of DPMI client!
trapno: 0x0e  errorcode: 0x00000006  cr2: 0x000a0000
eip: 0x08093c11  esp: 0xbffff6b0  eflags: 0x00000206
cs: 0x0073  ds: 0x007b  es: 0x007b  ss: 0x007b
Page fault: write instruction to linear address: 0x000a0000
CPU was in user mode
Exception was caused by non-available page
ERROR: leavedos() called from within a signal context!

Is this fixable with dosemu.conf ?
 
It have read about old Phar Lab . The string "Phar Lab" is in 
the program (not in the graphics TSR library):

> Copyright (C) 1986-92 Phar Lap Software, Inc.
> Copyright (C) 1988-91 Phar Lap Software, Inc.
> Phar Lap 286|DOS-Extender present
> Phar Lap 386|DOS-Extender present

But I wonder if that could be the problem.

I have tried to run it in console mode as root but 
I don't know how to configure my vga card in dosemu.conf 
I get a black screen if $_graphics = (1)

Thanks,

Julien

please try 1.2.1 -- a few corner cases related to this bug are fixed
there.

Thanks, it's working great with dosemu 1.2.1 indeed.
