Hi,
I'm using FPC 2.6.2 and {advancedrecords}.
The compiler shows a warning when I use a record variable. IMO this is
a bug because record variables need not be initialized, right?
Managed types (strings, interfaces, dynamic arrays) inside a record will
have a valid value (Nil), but other values will he garbage. The compiler
does not check whether a record contains any non-managed fields before
generating the warning.
Ok. But is this will be "corrected" in the next version? Because if
won't, I can not see sense to use it.
It seems that this was already corrected at least in trunk as a test
with 2.7.1 does not show a warning anymore. I don't know whether the
corresponding fix was merged to 2.6.3 though (I assume "no" by default
for compiler changes though).
The structure that does same but does not have this problem is the
object type. But is it used yet? I think Delphi make it deprecated,
right?
What do you mean "But is it used yet?"? And yes, Borland, Codegear,
Embarcadero, whoever decided that "object" is deprecated in Delphi in
FPC however they are still fully working and also benefit from newer
features here and then (mostly because "object" shares a lot of code
with "class" and "interface").
Talking about Delphi, it has the same problem with warnings on records?
Didn't test that.
Regards,
Sven
