FPC 3.2.2: Is TFPGInterfacedObjectList working correctly?

[antispam88]

Hi,

we want to upgrade our application working with fpc 3.0.4/lazarus 2.0.8 to the latest version 3.2.2/2.2.2.
In our app we are using interfaces (IUnknown) managed by TFPGList/TFPGMap. It worked as expected and we never had any problems regarding memory leaks.

But with fpc 3.2.2 our application is crashing regarding the TFPGMap. In the topic https://forum.lazarus.freepascal.org/index.php/topic,54089.0.html I have already got the hint to use TFPGMapInterfacedObjectData. But exchanging TFPGMapwith TFPGMapInterfacedObjectDatacauses an access violation.

I have created a test app with TFPInterfacedObjectList which throws also the access violation (fgl.pp 1197; TFPGInterfacedObjectList.Deref). Furthermore I have tested the code also with 3.0.4/2.0.8 getting the same access violation.

Is our use case not supported or is this an error in TFPGInterfacedObjectList/TFPGMapInterfacedObjectData?
Has anyone a solution for our problem?


Best regards

Please report a bug with an example that does not depend on the LCL.
