I use Linux x86_64

Code:

foo:
.start
      jmp .end        ;undefined symbol foo.end (does not work)
   jmp @f          ;undefined symbol @f (didn't work as downloaded, worked after assembling fasm)
@@:
.end:
     jmp .start      ;assembles fine
     jmp @b          ;assembles fine

Probably, because "@@:" is ending the scope of label "foo:".

Sorry, I didn't think through the example xD

Code:

foo:
        jmp .foo        ;undefined symbol foo.foo (does not work) 
.foo 
        jmp .foo        ;assembles fine

Code:

        jmp @f          ;undefined symbol @f (didn't work as downloaded, worked after assembling fasm) 
@@: 
        jmp @b          ;assembles fine

This report is probably related to the unsuccessful experiment with changing the selection of error to display. I will upload the reverted version tomorrow.

Version 1.69.48 for windows
Screenshots:
1. Everything ok.
2. Invalid instruction (sub ebx).
3. Duplicate labels.
In 2 and 3 screenshots fasm reports invalid entry label. And what is actually annoying is that when you write code at 1500 line, press Ctrl+F9 and it scrolls up to entry keyword, but error can be anywhere.
