Extracting the relevant parts of your crash report, it looks like it
crashed under Mac OS due to an invalid colormap. In GUI_init(), the
colormap is set before calling build_app_database(), so that should not
be the problem. The colormap is set by the line
cmap = Tk_Colormap(tkwind);
so my suspicion is that under Mac OS, unlike other systems, Tk does not
report a valid colormap initially, although it is supposed to do so. I'm
not really sure what to do about it, since it appears to be an error in
the Tk implementation for the Mac (Tk_MapWindow() doesn't actually wait
for the window to be mapped?). However, you could try changing line
9275 of tclxcircuit.c from
cmap = Tk_Colormap(tkwind);
to
cmap = DefaultColormap(dpy, DefaultScreen(dpy));
which may work to bypass the Tk structures and ask for the colormap
directly from X11. Let me know if it makes a difference.
