Any chance you can provide a smaller reproducer? Thanks.
No, every simpler testcase based on the attached code I tried
to create compiles successfully. Perhaps here is the problem?

Certainly *is* a problem if we hope to debug the issue decently fast...

I meant the cause of the problem is in its size, i.e.
there must be a critical mass of templates to trigger

Ok... Did you help yourself with delta? See:

A marvelous tool! I'm reducing it too,
staring at the proces with half-open mouth...

Note that a compiler built --disable-checking doesn't ICE, just errors out.
Thus, are you sure the code is valid, before anything else?

It compiles and works on gcc version 4.5.0 20090604.
The current compiler is
Configured with: ../configure

An even more reduced testcase which ICEs. Delta is amazing...
I think I'll stop here.
