Thanks for the report. Sorry for very late responce.

Supposedly, this problem has been fixed by the patch:
https://cygwin.com/pipermail/cygwin-patches/2024q4/012842.html

The problem is caused by very complecated mechanism, so it was
hard to reproduce the problem.

I could not successfully prepare build environment for LibreOffice,
therefore, I don't test this patch with building LibreOffice,
however, I hope this fixes that.

I would appriciate if you could test cygwin 3.6.0-0.216.g04f386e9af99 (Test)
or later.
