Hi,
for this largish testcase (reduced from a big one by Jakub) we ICE due
to error reporting routines re-entered. In 4_6-branch the situation is
worse, because for the original testcase we don't produce any useful
diagnostics at all before ICEing.
Thus the below, which seems pretty straightforward to me given that
unqualified_name_lookup_error, called by tsubst_copy_and_build (in turn
called by tsubst, called by dump_template_bindings) errors out
unconditionally.
Tested mainline and 4_6-branch. Ok for both?
Thanks,
Paolo.
