The regression reported in PR c++/8913 showed up starting with this
patch, which might merely uncover an existing problem:
gcc:

error_mark_node.

Wolfgang narrowed the window to a two-week period, and I'm working on a
script
to automate the search for a regression down to the hour when it was
introduced.
