gnupic: Thread: gpsim 0.21.2 crashes on MacOS 10.3

Hi everybody.
Today I intensively tried gpsim and It worked fine until I clicked into 
the symbols window to add a symbol to the watch. The app freezes for a 
while and exits with:

Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkSheet'

** CRITICAL **: file gtksheet.c: line 4356 (gtk_sheet_select_range): 
assertion `sheet != NULL' failed.

Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkSheet'
Bus error

Anybody experienced this before? Is it a problem because of the 0/NULL 
thing we are heavily discussing? Or am I doing something wrong? Or is 
it my gtk? I have no idea, but maybe you guys.

I installed gpsim with the help of the fink files from Mikey Sklar. 
Would be cool if anyone could help me. gpsim look pretty cool to me.
Thanx,
Ezra.

Just tried and I get the same error the moment I select a symbol in the 
symbols window. So it's not specific for your environment...

Michiel

If either one of you can send me a gdb back trace, I'll look into this.

I get the same behavior as Easy B, and Michiel. gdb changes things a bit,
but this is what I managed to capture.

oops

gpsim should only be invoked with a .cod file or a .hex file - not both!

gpsim -s led_jumpsui.cod

Mikey I see two problems in the back trace. 

Maybe we should take this offline, but could you try applying these two 
patches:

Thanks

Good to see the reaction. I'll be ready for testing.
Thanx,
Ezra.
