gnupic: Thread: gpsim-0.21.1 crash

gpsim 0.21.1 crashes in popup_activated.

Building gpsim with -ggdb shows that popup_sbow->gp is not a valid address, 
sometimes NULL, and sometimes a bogus pointer. The attached zip file has 
'crash.txt' containing output from gdb.

I'm not a C++ programmer, but it doesn't seem right that 'ptype popup_sbow' 
shows that it has no member named 'gp', and yet 'print popup_sbow->gp' 
outputs a value without complaining (although it's not a valid value).

gpsim 0.21.1 always crashes at this point (gui_src_opcode.cc line 209)
  pm_size = popup_sbow->gp->cpu->program_memory_size();

gpsim 0.21.0 runs fine. g++ is version 3.3.1 on RedHat Linux 7.2.
Any help is appreciated.

Thanks,
Jeff

I can almost gurantee that this has been fixed and checked into CVS. I'm 
going to try to get an 0.21.2 out this weekend.

I can also guarantee that I can't spell...
