Turning off the toolbar makes the crash go away, so I suspect a GC
problem with building the tool-bar string.

It could be a specific tool-bar binding in one of the keymaps that
triggers the bug.

Could we try to dump global-map, and all active local maps and look
for tool-bar items (using eval) in them ?

Does Cygwin use GCPROs or stack marking?
