To reproduce:

  1. Open any object painter
  2. Add new function
  3. Type "throw" into Function name field
  4. tab out/click anywhere
  5. PB closes immediately without any warning

Happens in 2019R3, can't check other versions. The same thing happens with "throws". Using edit source to change a function name to "throw" or "throws" errors out with "Syntax error" instead.

With other reserved words you just get a warning, I get the feeling this shouldn't happen.

Hi, Benjamin -

Please examine the PB 2019R3 Help topic titled "reserved words". It clearly calls out which reserved words can be used as function names and which ones cannot.

Best regards, John

Hi John,

I'm perfectly fine with not using reserved words as function names but I don't think they should crash the IDE regardless. :)

You are right John. But the issue with this specific word is that the ide crash. With other reserved words you are notified that you should change name. Putting something that isn't valid should not crash the ide...

Hi.

I do see that behavior. Only exception is global functions, where the ide doesn't crash. I also tested in PB 2022 R3, and the crash happens even there.

You can open a support case for that (New Bugs | Appeon)...
