I don't get this SIGRAP when I run the same command.  The program just 
runs to completion.  Maybe someone can explain what might cause this.  I 
have no idea.

The one thing that strikes me about this is the large number of "asy" 
threads.  There was a recent bug report about multithreading in 
cygwin-3.5.3:

   https://cygwin.com/pipermail/cygwin/2024-May/255987.html

Can you try installing a 3.4.x version of cygwin and see if you still 
get the hang?
