Thanks.  Your backtrace looks strange: was that binary stripped or
something?  Why does the backtrace end at CHAR_TABLE_REF, which is a
very internal function?  Why the "??" in the backtrace?

Are you sure you were in the right thread when you collected the
backtrace?

A this point, we need as many informative backtraces as you can
provide.

(Btw, the other Cygwin-64 related crashes were in the w32 build, not a
GTK build of the Cygwin Emacs.)
