Both codes look correct and should be possible. Did you check your project by changing the Target to another type of PLC PLCWinNT for example?

Here are 2 different ways to access the output variable of a FB. It looks similar but it seems that the 2nd one cause crash.

I had the problem with REAL variables. It is Ok with the 1st method.

I am using the Coldfire compiler.

Is the 2nd way correct?

MyFunctionBlock(VarInput1:='aa', VarInput2:=22, VarOutput1=>LocalVar1, VarOutput2=>LocalVar2);
IF LocalVar1 THEN
  x := LocalVar2 * 3;
  ...
END_IF
...

MyFunctionBlock(VarInput1:='aa', VarInput2:=22);
IF MyFunctionBlock.VarOutput1 THEN
  x := MyFunctionBlock.VarOutput2 * 3;
  ...
END_IF
...
