// allocator to avoid Win32 issues.

////////////////////////////////////////////////////////////////////
// Class : epvector
// Description : Unfortunately, on Windows, std::vector can't be used
// for classes with explicitly alignment requirements,
// due to a minor mistake in the template definition
// (one of the vector methods receives a concrete
// object, which the compiler flags as an error, even if
// the method is never called).
//
// As a workaround, Eigen provides their own
// specialization of vector, using their own aligned
// allocator. We define that here as epvector, which is
// meant to be a drop-in replacement for pvector for
// classes that include a linmath object that requires
// alignment. Unfortunately, this means we can't use
// the Panda allocator, so memory allocated for this
// vector class won't be tracked as part of Panda's
// memory tracking system. Them's the breaks, kids.
