Eventually I have caught a bug that bothered me in a few latest versions of Smath.

critical_bug.sm (4kb) downloaded 20 time(s).


Try to delete the first number "4" in front of the ratio.

Step 1: Select it with the cursor.




Step 2: Press "Del", the "4" turns into a black square.



Step 3: Press "Del" once again. SM pops on "Critical error".

Jean,
It can't be doctored, it is not a calculation issue.
Smath Studio crashes at the moment you push "DEL" key to delete this number "4" or whatever else there.

Confirmed. I also came across it, but I didn't investigate it. SMath Studio 0.99.7921.69.

It didn't surprise me that Jean couldn't understand what the bug is.

Jean, what you're trying to do here is destructive. You prevent users from helping developers improve the program, that is, you bring harm. You don't have to do that. This is not good.

Jean, in the exUSSR there was such a norm as forced rest. People who worked hard were forced to rest in a sanatorium. And their leaders, who allowed this, were punished. I think you need to go to a sanatorium and temporarily stop working here. I don't want to be punished and I can give you a rest.

Is it possible to combine both: part script style & equation editor ?
As well as accommodate both styles in program ?
Cheers ... Jean.

And yet another useless not related post again.
Unbelievable. Wow, just wow.
Such ignorance, such obstinate, such thick head...
I am out of speech right now.

Unfortunately,
The "Critical Error on Del key action" was not fixed yet in the latest stable version.
Try to delete "g" by using DEL key.
oldbug.sm (3kb) downloaded 13 time(s).

Greetings!

I can also confirm the existence of this issue ( "v0.99.7921.69" ). Upon investigation, I have (2) items:

  1) The program does not actually 'crash', the program is still running. Thus: you can recover from this bug without losing all your work!
      a) To recover from this error:
            1) On the " Unhandled exception has occurred ... Index was outside the bounds of the array" popup error message, Click on the button: 「Continue」
            2) 'UNDO' your last action, either via the menu bar: 「Edit」 -> 「 Undo」 or via keypress 「Ctrl」 + 「Z」
            3) Repeat steps #1 and #2 until you achieve a successful 'undo'.

  2) The elements of this error seem to require a grouping operator (e.g., Absolute Value, Parenthesis, Determinant, Square Root, Matrix) that is paired with a fraction/division operation, prepend this with a multiplication statement and you can duplicate the error. See screen capture below:


Below are a few statements I compiled; performing the double-delete on the integer '6' will throw the same error:

Greetings,

I found another configuration that can trigger this error; if you declare/evaluate a variable, and then try to multiply that entire set: you get a syntax error. Now if you attempt to correct the statement by using the [DEL] to remove the evaluation, the error gets thrown (as shown below):

   [SMath]Critical_Error_Occured.jpg

The work around would be to use the [Backspace] to delete/correct the equation, or to copy/paste the terms into a new statement without syntax errors.
