v4.80 bèta: string concat problem using '+' (OK, my fault)

Please ignore this post. It was entirely my fault. I oversaw that " StrCat(S1, S2);" made S1 too long to be concatinated with S2 into S3. Soooo sorry!

Hi, in v4.80 bèta I have seen in the software debugger a string concat problem:
Testcode:

Code: Select all

Var S1, S2, S3: string[10];
...
  S1 := 'xxxxxxx';
  S2 := 'yyy';
  S3 := 'zzzz';
  
  StrCat(S1, S2);                 // Ok , result = 'xxxxxxxyyy' + ending 0
  
  S3 := '';
  S3 := S1 + S2;                  // wrong, result = 'xxxxxxxyyyy' (no ending zero, 4 times 'y')
                                  //      side-effect: S2 becomes 'yy' (1 character shorter)
                                  
  S3 := '';
  S3 := S1 + 'yy';                // wrong, result = 'xxxxxxxyyyy' (no ending zero, 4 times 'y')
                                  //      side-effect: S2 becomes 'y' (again 1 character shorter)

Also seen in mP dsPIC v4.80 bèta.

I can not really believe that above is true. Can someone confirm (or deny) this?

Thanks in advance.

I am so happy that it is not something in the compiler, only one stupid me...

Soon, I hope, all discovered errors will be solely our own .
