This exchange illustrates the problem rather nicely. Its not clear to me from the name "aligned_storage" that its meant to do the same job as "stack_allocate" and in fact is easily confused with other boost functions. I've been able to find no documentation nor test nor other information. The only place its used is in variant.hpp but its not mentioned in the documentation of that either. There is no statement in the header itself as to what it does and the code is sufficiently non-trivial that it's not obvious what its supposed to do. The fact that it has a parameter than stack_allocate doesn't need also suggests that it's intended purpose is different from that of stack_allocate.
It doesn't, see aligned_storage's "Rationale" subsection in http://tinyurl.com/39asx. -- Aleksey Gurtovoy MetaCommunications Engineering
