Labels and compilation error bug thing

Step 1: run this in slot 0

@A
PRINT "Hi"

Step 2: run this in slot 0

@A@'something that contains the previous label and causes a syntax error

Step 3: run this in direct mode:

GOTO @A

It will print "Hi". Apparently you can use this to crash SB somehow.

For more explicit instructions: Step 1: Run this in slot 0:

@A B$="Hi":PRINT B$

It runs fine. Step 2: Run this in slot 0:

@A@B$="Hi":PRINT B$

It generates a Syntax Error. Step 3: Run this in direct mode:

GOTO @A

The 'direct mode' cursor stops blinking for a couple of seconds. The system shows "An error has occurred, forcing the software to close. The system will now restart. (Unsaved data may be lost.)". Not every syntax-error-causing code in step 2 will cause this. New 3DS, SmileBasic 3.3.2.

I tried it myself and this is the result:

My first conclusion which seems incorrect

(? / PRINT) B$ doesn't matter here. This can be omitted. I think SB gets confused rather if @B$ is a label or a variable and (, what SB always does,) crashes. (It doesn't matter if B$ got something in the 1st place. I tried it after SB crashed and the results were the same.)

Old 2DS, SmileBASIC EUR 3.5.2 It turns out the "$" sign is placed in a way where SB gets confused whether "@$" is a label or a string variable. Leaving @ and/or $ alone without alphanumerical symbols, will end up crashing SB, once you run the program and come to that point in direct mode like: >=Input [Blank]=Output

 OK
