dcc32 Fatal Error F2084 Internal Error: AV116B241E(11640000)-R00000378-0

I'm using Delphi (Version 28.0.42600.6491).
Often (about two times per day) when i'm working, i get this error when trying to compiling any project. Only workaround is to close the IDE and open it again :
dcc32 Fatal Error F2084 Internal Error: AV116B241E(11640000)-R00000378-0
It's not a big deal but this happens everyday.
Any hints to fix it for good ?
Thanks !
it uses to happen alto to me... i have no ideia what can lead to this ERROR but in my case i found that it was triggered on a function where i was comparing to TObject members of a class
IE: Self.Parent=NewComponent.Parent
my solution was to find a work arround to eleminate the Object comparison and use other datatype reference for comparison

Delphi and Firebird - Error: “Attempt to reopen a open cursor”

In a Data Module I put a SQLDataSet and will be for the SQLConnection. In the "CommandText" property I'm using the line:
select * from tblusers
When changing the "Active" property of SQLDataSet, it returns the error "Attempt to reopen an open cursor" or "unknown ISC error 0". The latter occurs once, on the first attempt. I'm using Delphi Rio 10.3 and Firebird 3.0 Dialect 3.
I went back to Firebird 2.5 and I didn't get the error with SQLDataSet anymore, the connections went back to normal. I believe there is some incompatibility with the new Firebird 3 Library.

unable to extract model type swift

I'm having a slight issue with CoreML using Swift Playgrounds while attempting to make a gender classifier model. When I add the Gender.mlmodel and Gender.swift to their respective folders within the Playground Page (Resources/ and Sources/), I get a rather peculiar error, shown below:
Fatal error: 'try!' expression unexpectedly raised an error: Error Domain=com.apple.CoreML Code=0 "Unable to extract model type from stream in compiled model: Error opening file stream: /var/folders/kt/11b_lk412hv327qjhvgnhvzr0000gn/T/com.apple.dt.Xcode.pg/auxiliarymodules/7C17E9A3-54C7-4828-96BD-00AE07EC7F3E/Gender_Classifier_PageSources.framework/Resources/Gender.mlmodel/coremldata.bin: unspecified iostream_category error" UserInfo={NSLocalizedDescription=Unable to extract model type from stream in compiled model: Error opening file stream: /var/folders/kt/11b_lk412hv327qjhvgnhvzr0000gn/T/com.apple.dt.Xcode.pg/auxiliarymodules/7C17E9A3-54C7-4828-96BD-00AE07EC7F3E/Gender_Classifier_PageSources.framework/Resources/Gender.mlmodel/coremldata.bin: unspecified iostream_category error}: file /BuildRoot/Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-900.0.74.1/src/swift/stdlib/public/core/ErrorType.swift, line 181
I've thought that it had an issue accessing the file itself, so I tried using different locations and the absolute path as a String (which returned a value when force-unwrapped), but to no avail. In addition, I tried other models that I know are able to be loaded (SqueezeNet.mlmodel), and that did not work as well, returning a comparable error.
I appreciate any help that anyone would be able to offer, I'm completely perplexed by this issue. Thank you!
I found the solution to this: apparently Swift Playgrounds does not compile .mlmodel to .mlmodelc, thus causing the failure to read a non-compiled model. For anyone else wondering, just run MLModel.compile(at: URL?) to convert it to the compiled format.
In Swift 5.2.3, the following is correct.
let url = try MLModel.compileModel(at: URL(fileURLWithPath: "<#/path/to/read/model.mlmodel#>"))
let mode = try MLModel(contentsOf: url)

Delphi 7 QuickReport Preview Error

Im using Delphi7 and QuickReport 3.
Im new to Delphi and QuickReport.
When I debug my application I got an error at the procedure TQRPreview.UpdateZoom;
if assigned(FQRPrinter)
The exception is Access violation
In my form Im calling , QuickRep.Prepare;and QuickRep.Preview.
When Im calling QuickRep.Preview I'm geeting the error.
Any help is appreciated.
Double check your code when you are creating some form with that QReport. You are freeing it after it is no longer needed.
Secondly, try to add Application.Processmessages; after you're done with any printing.
