Note, 4_1-branch is closed. I would suggest first trying a newer compiler on
your code, e.g., 4.3.2.

Which I guess is invalid because the definition of Cdeque is not complete
at the time we bind iterator::pointer to Cdeque<T>::pointer.

Subject: Re: [4.2/4.3/4.4 Regression] seg violation
Hi,
thanks for taking the time to look at my problem.
I did try with version 4.2 and fared no better.
Versions up to 4.0.x compile ok.
Let me know if I can be of further assistance as I am quite stuck at the
moment.
Best regards, wdoeringer

Subject: Re: [4.2/4.3/4.4 Regression] seg violation
Hi,
I have added some substance to the reduced testcase, so that now actual
code is generated. You find it in the attached file.
It compiles well under g++ 4.0.1 (Apple Inc. Build 5456)
but crashes under
4.2.1 (Ubuntu 4.2.1-5ubuntu4) and under 4.1.3
Best regards, wd.doeringer

This is not an issue because Cdeque<T>::pointer is a member of the current

The failure happens because structural_comptypes calls resolve_typename_type,
while merge_types does not. Maybe it should as in this patch?

But I suppose you want consistently t1 here ;)
