We are trying to do something called "debugging" here and you are not
making it especially easy.  If you could somehow test the above, it
would give us a data point that might be a clue as to what the problem
could be.

You are talking about upgrading to 1.5.25-15 but presumably you upgraded
more than just the DLL so there are a quite a few possible other
candidates.

If you are really just swapping back and forth between different DLLs
then you need to provide EXACT details of what you are doing.  You have
not provided cygcheck output although I did point you to the problem
reporting web page which asks for that.  cygcheck output for the working
and non-working systems would be useful.
