This is a Lazarus issue, not FPC.

Should I re-enter it or can I edit this one? (This is the first time I book an issue)

Without waiting for an answere he already opened a new ticket in Lazarus.
Can some devel resolve this as duplicate of 0031532 and then close?

> @Thaddy: This is a Lazarus issue, not FPC.

Why do you think so?


It's a regression and it happened when switching from FPC 2.6 to 3.0:

Lazarus trunk + FPC trunk: BUG
Lazarus trunk + FPC 3.0.0: BUG
Lazarus trunk + FPC 2.6.4: works fine

So it's an FPC bug or Lazarus sources have to be fixed for FPC 3.0.0 changes.
