Strange issue with new firmware [SOLVED]

[periappi]

Hello,

I'm encountering a strange issue with the new firmware. Indeed, whereas my old programs used to work on the former version, they don't anymore, and for something weird : the Prime doesn't seem to like the characters "/" and "\".

For example : in the function
RETURN("/!\ n < 30 /!\");
The debugger stops on "/" and "\".

NB : I tried to use pragma_mode, but it doesn't change anything.

Can you help me ?

Thanks,
