A pointer to a local VPS is passed as reference into the parameter set manager, which takes ownership of the object.
When the local scope is left, the memory will be freed, which can lead to use after free (and double free).

Changes include:
- use [[maybe_unused]] instead of cast to (void)
- use generic lambda function and remove related comment about C++11
- update MSVC version check
- don't condition '#pragma once' on MSVC version

Avoid having a separate PTL count since we already have a size
for the vector containing the PTLs.

Add a size check to avoid writing into inexistant PTL. This may
avoid bug reports such as #1587
