>> 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.

(1) Keeping asymptote 2.88-1, I tested with packages rolled back:
Package Version Status
cygwin 3.4.10-1 OK
cygwin-debuginfo 3.4.10-1 OK
dash 0.5.12-2 OK
libunistring-debuginfo 1.1-1 OK
libunistring-devel 1.1-1 OK
libunistring5 1.1-1 OK
tar 1.35-1 OK
uname -svrmo 
CYGWIN_NT-10.0-22631 3.4.10-1.x86_64 2023年11月29日 12:12 UTC x86_64 Cygwin
Then, `HOME=/tmp asy -vv -f pdf test` hanged.
But, asy invoked by gdb did not hang...
(2) asymptote 2.85-1 with same packages
(ignoring warning about texlive 2024):
Then, `HOME=/tmp asy -vv -f pdf test` hanged.
But, asy invoked by gdb did not hang...
(3) asymptote 2.85-1 with packages (latest except asymptote)
(ignoring warning about texlive 2024):
Package Version Status
asymptote 2.85-1 OK
cygwin 3.5.3-1 OK
cygwin-debuginfo 3.5.3-1 OK
dash 0.5.12-5 OK
libunistring-debuginfo 1.2-1 OK
libunistring-devel 1.2-1 OK
libunistring5 1.2-1 OK
tar 1.35-2 OK
CYGWIN_NT-10.0-22631 3.5.3-1.x86_64 2024年04月03日 17:25 UTC x86_64 Cygwin
Then, `HOME=/tmp asy -vv -f pdf test` hanged.
And, asy invoked by gdb got a siganl SIGTRAP and stopped.
Rolling back cygwin packages has almost no effect.
Very weird... 
Now, I suspect any recent Windows Update might have to do with the issue...
(just because no other idea comes to me).
Not confirmed
