Happens on Windows 32 and 64 bit.
Only with debug build.

Error doesn't happen when I move code from library to the application.

Here is reduced test case (where 2 errors happen, 4 files):

Here is smaller case (only 1 error, 2 files):

No idea exactly what causes it, but here is another place I've seen it:
