Hi,
When editing SQLtext in a TSQLQuery-component and when getting an
error in the SQL, Lazarus 2.0.12 dies. Anyone seen this behaviour on
Windows 10 running a PostgreSQL 12 connection?

Br,
Niclas

Not when changing the SQL-Property.
But Lazarus gives me an Access Violation, when i have a TSQLQuery-
Component, which is set to active in the OI, and when i try to set it
to inactive in the Object-Inspector, Lazarus goes BOOM.

Bottom Line: Don't set anything of the TSQL-Trinity to active in the
OI. Only from Code.

Have you reported this as bug? Is it specific to a DB component set?

It is already reported many times. See :

and its related issues.
Particularly nasty to fix.

It's fixed in FPC trunk.

Does it not need any changes in Lazarus components? Maybe not, good
so!
The reports, or at least one of them, can be open for a while.
Otherwise somebody will report the same issue again.

I spent almost an hour fixing the issue, when I noticed that the bug
is already fixed.   Another hour wasted...

in BufDataset.pas(FPC).

Thank you all for your responses. So, just have to wait for the bugfix
to be released. 

Cheers,
Niclas
