Is this a combined MS Windows/X Windows build? I would guess that
what's happening is that XEmacs is confused about where it's trying to
print.
Is this a debug build? Unoptimized? If not, building with debug
symbols, and maybe without optimization, would allow a more useful
backtrace, I think.

That doesn't tell me much, it's all deep in Cygwin.
At that point you could try sourcing src/.gdbinit, and then use "lbt" to
generate a Lisp backtrace. We can hope that will localize the problem
to a particular part of the C code.
