segfault in force_to_data() inside gdk_colormap_sync()

[Michael Rothwell <rothwell holly-springs nc us>]

I've got a small gtk app that I've compiled on my desktop, and copied to 
a small laptop (486/100, 640x480 screen, 24MB RAM). It has 
gtk+-1.2.10-11. The desktop has gtk+-1.2.10-ximian.25.

On the laptop, the program crashes inside of gtk_init_check (and 
gtk_init, if I call that instead). I don't know why.

gtk_init_check()
gdk_colormap_get_system()
gdk_colormap_sync()
force_to_data()

This is an 8-bit display.

Does anyone have any thoughts? Tips?

Thanks,

Michael
