RE: [Boost-Users] Re: pool_allocator problems on VC7.1 (real rele ase)
-----Original Message----- From: John Harris [mailto:john.harris@tradingtechnologies.com]
Since it seems to work on VC7.1, it would be nice if the author had access to that compiler and could do some testing. In the mean time, I'll try some stuff with this new toy and report any further problems.
Some command-line tools ship with their DDK, so I do have a version of "cl.exe" that reports "13.00.9176" - no idea how this fits in with the VC versions, though. And the DDK doesn't include an STL anyway. There is one "common" failure case with some implementations of STL containers: passing 0 to Allocator::deallocate. When used with std::allocator, the 0 is passed through to operator delete() which of course ignores it. When used with pool_alloc, this generally causes a segfault. IIRC, STLPort's std::vector will do this if you construct & destroy an empty vector. Since I don't have the VC STL, could you do that test case for me? Thanks, -Steve

Unfortunately that's not it (it's the final beta); You want 13.10.3077.0.

I can test this for you tomorrow (I'm about to go drinking now). In return, could you possibly tell me how to change pool_allocator so that it uses my own tag? My goal is to have a totally local allocator for some special parts of the code. Why, BTW, does it have to use the Singleton pool interface instead of the object pool interface? The latter, I think is what I'm after. I'll reply here with the results of my test. jh

I tried several variations on vectors and lists with pool_allocators, constructed with ints and basic_strings (themselves with pool_allocators), in both debug and release builds, and had no crashes on VC7.1 Release. jh
