[boost] stack-based std::containers

I have functions like say a quartic equation solver that can return a 
variable number of solutions.  It would be clean IMO to return or pass 
by reference a std::vector or like container that store the solutions. 
However heap allocation is fairly expensive here so the usual solution 
is to have a local array with max solutions elements and pass that by 
reference into the solver and return the number of solutions.  This is 
ugly to use and read.  Is there a library for stack-based std-like 
containers?  Alternatively is it possible to make an compatible 
stack-based allocator for std::vector using alloca?

Thanks,
