Sure.  Why should't it?

Looks like the same.

and so on and so on.

It does not make a lot of sense to report all these one by one and hope
that magically this will get stuff fixed.

It's pretty clear that someone has to actually _work_ on getting this
stuff through and classify which problems are due to the C++ library,
which are due to bad usage in LilyPond, and supply fixes to _both_.

So you better find someone who actually cares about that
compiler/platform/library to get to work on it.
