child_info_fork::abort: cygpng16-16.dll

[Jim Reisert AD1C]

On one of my computers (but not the other), I get this error when I
try to start Emacs 29.4 in an xterm:

      0 [main] emacs-gtk 2079 child_info_fork::abort:
\??\D:\Cygwin\bin\cygpng16-16.dll: Loaded to different address:
parent(0xCB0000) != child(0x25E0000)

I killed the X server, started a Windows shell, started ash, then
called /bin/rebaseall

Work was done, but the problem persists.  What should I try?
