So I want to install my own assertHandler. The problem is, that even if I call "setAssetHandler" in a shared module constructor, and that module does not import any other modules, it is still not initialized first. Is there a way to set the assert before any module constructors run without hacking druntime? Kind Regards Benjamin Thaut

Is there a way to set the assert before any module constructors run without hacking druntime?What is your use case? Do you want to use assert in a module constructor? Or is it when running unit tests. I mean, why can't use set it in "main". If it's for unit testing, could you setup your own unit test runner that calls "setAssetHandler" before running the tests? -- /Jacob Carlborg

(Well not directly, but functions I call in a module constructor use assert). On Windows x64 I want to use the CrtDebugReport to display any failing assert and I want this to happen for all asserts and not only for asserts that happen after main started. -- Kind Regards Benjamin ThautSo I want to install my own assertHandler.
