I tried your test case but got the following validation errors instead
of a segfault:

sample-lamp.xgtf:24:50 error: Unknown element 'data:polygon-type'
sample-lamp.xgtf:24:50 error: Attribute 'open' is not declared for element 'data:polygon-type'
sample-lamp.xgtf:49:66 error: Duplicate unique value declared for identity constraint of element 'sourcefile'.
sample-lamp.xgtf:232:51 error: Unknown element 'data:polygon'
sample-lamp.xgtf:232:51 error: Attribute 'framespan' is not declared for element 'data:polygon'
sample-lamp.xgtf:240:29 error: Element 'data:polygon' is not valid for content model: '(null,)'
sample-lamp.xgtf:476:57 error: Duplicate unique value declared for identity constraint of element 'sourcefile'.
sample-lamp.xgtf:485:57 error: Duplicate unique value declared for identity constraint of element 'sourcefile'.

I could find neither data:polygon-type nor data:polygon elements in the
schemas you provided so clearly your sample XML is not valid per your
schemas.

Can you send a valid XML document that I can use to reproduce this
problem? But before you do, can you confirm that you've compiled
all your schemas with the --generate-polymorphic as suggested by
the warning? If that's not the case, then please try to add this
option and see if problem goes away.

Thanks,
Boris
