I know where the problem is.  A new piece of code fixing a crash due to
a buffer underflow is too aggressively guarding the path buffer against
this underflow when normalizing ".." in Win32 paths.

I'll fix this and release a 2.11.1 soon, but I still have a question:

Why do I push out test releases if nobody cares?

In terms of this OCAML build system problem:

Please fix your build system.  Do not mix POSIX and Win32 paths, use
POSIX paths only.  Backslashes are *no* drop-in replacement for slashes.
Some of the path handling is seriously crippled as soon as you start
using backslashes, and that's a delipberate decision and won't change,
even after fixing the aforementioned bug.
