Segmentation fault when examining memory in debug mode

[GoogleCodeExporter]

1. Start Virtual AGC in debug mode:
yaAGC --core=Colossus249.bin --cfg=CM.ini --debug
2. Try to examine register A with command "x A". The yaAGC immediately quits 
with segmentation fault. "x 0" or "x L" or "x 1" also result in segfault.

I've built my yaAGC from source yaAGC-dev-20100220.tar.bz2, op.system is 
Debian/Lenny

Seem to me the reason for this behaviour is an unhandled nullification of a 
string variable at agc_gdbmi.c:1709  
   if ((s = strstr(s,"/")))
which ends up in a segmentation fault at agc_gdbmi.c:1716, where the variable 
"s" is referred.
