Hello,
I'd like to know if this is a known issue, or a new bug.
With the following code:
------------------
program tester;
type SomeType = ( SomeElem );
const ElemSet = [ SomeElem ];
begin
writeln(SomeElem in ElemSet);
writeln(SomeElem in (ElemSet + []));
end.
------------------
one gets:
TRUE
FALSE
while it should rather be
TRUE
TRUE
The problem concerns FPC 2.2.0 on i386/Linux. Actually, I was tracing a
bug that was only visible with 2.2.0 while the 2.0.0 version of the
compiler did not produce an errorneous code on that. Unfortunately, I
didn't succeed to separate a small snippet of code responsible for that -
in that case, however, the set after the '+' was another set constant, not
an empty set, so the problem is rather general. As I said, with 2.0.0 the
boolean value was correct, while with 2.2.0 it was plain wrong.
Best regards,
Adam Naumowicz
