I noticed this in your cygcheck output:

Why are you text-mounting it?  Is your current working directory
somewhere under that text mount?  It may be a bug in tar's handling of
text-mounted files (ideally, tar should be reopening everything binary
in spite of text mounts, but I may have missed a spot).

Could be an accidental regression in my cygwin-specific patches between
the two versions. But I don't normally use or test on text-mounts, so
I'll need confirmation that you are indeed experiencing the problem only
in your text mount, before I spend cycles debugging it.
