It’s okay in Racket BC.

I’m not near a computer Does it happen from the command line? (Without DrRacket ) You can also try DrRacket from the command line to check for error messages If you can document and log in github racket/racket or racket/DrRacket that would be great

@spdegabrielle Tried DrRacket from command line and still no error messages.

No problem on racket repl.

After some experiment, I found that it’s due to memory limit: 128 MB, if I set to 256 MB, it works just fine.
