I'm happy to debug this, if you can get me an executable to work with.
Large is fine, just something you can share.

As far as the patch goes --- we probably want to use a complaint here;
see 'complaints.h', and see how they're used in dwarf2read.c.  That
will automatically limit the number of times you see the complaint,
the default being zero.
