Debugger not breaking on 4.0b8 on MacOS Monterey – Depends on file name. #486

Created by: alsmithson

• I opened a sketch written by someone else and tried to use the debugger. It would not break on any line.
• I reduced the code down to 6 simple lines and it still would not break.
• I copy/pasted the code to a new, blank sketch, and breakpoints did work.
• After saving both files that only had 6 lines of code, I looked at the code with Atom and DiffMerge. Neither could find a difference except for the file name.
• I renamed the two files to good.pde and bad.pde and renamed their parent folders to match. Now both sketches break correctly.

I have another sketch by the same author with the same behavior. I could not see anything odd in the file name (though it did use underscores). I copy/pasted the file name into Atom and looked at the Hex code. Nothing was out of place, but I’m not sure my Mac did not do a conversion in the clipboard. The author speaks Spanish and lives in the Canary Islands, so maybe his keyboard is different from mine.

I have a workaround (renaming all files), but I wanted to report this odd behavior.
