I still think this is the same underlying bug:
a) I reduced Wolfgang's version to come up with mine.
b) My example starts with an ICE in
     cxx_incomplete_type_diagnostic, at cp/typeck2.c:278
   which changed to
     instantiate_class_template, at cp/pt.c:5440
   the day Wolfgang's testcase started crashing the compiler.

Btw, I've got another reduced example - this time the crash is in the same
spot as with the original example. For this one I also get
: Search converges between 2003-01-15-trunk (#165) and 2003-01-17-trunk (#166).
