Re: Explicit instantiation failing in 3.5 (boost)

[Carlo Wood <carlo at alinoe dot com>]

It should be impossible that this gives an error about allocators.
That added to the fact that the allocator code was recently
heavily changed in this regard - I am fairly sure that this is
a bug in libstdc++.

Would you be so kind to report it to http://gcc.gnu.org/bugzilla/  ?

Thanks,
Carlo Wood
