Summary
Debug string is not displayed in console if start with more than 14 hyphens. Same behavior if final '\n' character is missing.

Example:

#declare s_ = "----------------- DEBUG -----------------------------"; // String is not displayed in console
#debug concat(s_, "\n")

number of hyphens is matter - threshold is 14:
#declare s_ = "--------------"; // This works
#declare s_ = "---------------"; // This not

FWIW. I'm not seeing the issue on my Ubuntu 22.04 linux machine with the v3.8 based compiled versions I have in hand.

I don't use Windows so I'm unable to try the posted code in that environment.

If I recall correctly from my Windows days, 15 or more hyphens in a row creates a horizontal rule. Do you observe this behavior?
