#3334 ucsim: dump xram with 8-bit hex values crashes s51

[Mike St]

I created the following startup script and saved it as abc.cfg

#to stop stack overflow
b iram w 1 if "sfr[81]==0x7F"
com 1 di 0x70 0x7F

#Memory bank system
#so simulator sees 512K ram connected to P2.0-P2.5, P1.0-P1.4, P0.0-P0.7
#make 512K big chip
memory create chip BIG 0x80000 8 

#Bank at Port 1, Ram access 14-bits a bank
memory create banker sfr 0x90 0x1F xram 0 0x3FFF 

#Bank binding: begin at 0 in xram space. Do each value

#break+show result on command proc

com 2 dump iram 0x30 0x4A

I then start the simulator (ucsim 0.6.7) using the command "s51 -C abc.cfg"

Then I execute the following line:

dump xram 0x2F 0x3F

I receive a "segmentation fault" and the program exits.

sorry I'm a bit new to this site and only know how to post feature requests and bug reports.
Will you be releasing another source package on your website?
