/**

|
* 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.
