Re: Strange crash with multiple inheritance when overriding a virtual from a templated base class (VC++ 2005)

Possibly me being daft, but does anyone know whether the code below
should work please? (It's a minimally compileable example of an issue
I'm having in my real-world code, so my curiosity isn't idle in this
case.) It crashes on VC++ 2005 (I know it's quite old now -- I'm waiting
for VC++ 2010 to come out :))

It doesn't crash if either:

(a) B isn't a template
(b) I replace the B::f(i, s) in D::f with B<int>::f(i, s)
(c) I change the inheritance order via struct D : B<int>, I

This puzzles me! (b) made me suspicious that my syntax was to blame, but
online Comeau compiles it without error.

Any thoughts please? What am I missing?

Cheers,
Stu
