Looks like your compiler can't handle the conversion even though it's
defined in its base class, gcc 4.3+ (supposedly more std conforming)
handles it fine. A workaround is to an explicit conversion as a copy
ctor in the CellCacheAllocator like this (untested):
template <typename U>
CellCacheAllocator(const PageArenaAllocator<U, CellCacheArena> &other)
: Impl(other) {}
Let me know if it works for you.
