When static_assert() is used in a C++ class, doxygen seems to stop parsing the file at that position.

All entities that are documented above the static_assert appear just fine in the documentation, all entities below don't.
If the static_assert is removed (or put in a comment), everything works fine.

The output (QUIET = NO, WARNINGS = YES) show no errors about this.

In my case, the static assert looks like this (where RESERVED and BITSIZE are constexpr defined above, so nothing fancy here):

static_assert(RESERVED < BITSIZE, "Too many bits reserved for special use.");
