Hi! I try to use boost::pool_alloc with STLport-4.5-0119 snapshot. STLPort call pool_alloc::allocate(const size_type n) with n = 0. STLPort naitive allocator returns in such case NULL, but pool_alloc tries return memory.
Hmmm... You seem to have uncovered a corner case, not covered by the Standard requirements. I will change the pool_allocator (and fast_pool_allocator) to be able to handle this by returning NULL.
Method simple_segregated_storage<SizeType>::try_malloc_n( void * & start, size_type n, const size_type partition_size) has problem too if parameter n is 0. Problem is in while condition: while (--n != 0)...
This is correct; (n > 0) is a precondition for that function. -Steve
