RecordSaveJson raises AV

Hi,

can anyone confirm, that a simple console app, only containing

Writeln(RecordSaveJson(Executable, TypeInfo(TExecutable)));

will raise an AV...

Zugriffsverletzung bei Adresse 00000000 in Modul 'IT.exe'. Lesen von Adresse 00000000

( AV at 000000 in module ''. reading address 00000)

mORMot2, current version (GitHub)
Delphi 10.4.2, Win32

Regards,
Daniel

Re: RecordSaveJson raises AV

What is Executable?
Do the regression tests pass on your computer?

Re: RecordSaveJson raises AV

What is Executable?

From mormot.core.os, aka ExeVersion (mORMot 1).

Do the regression tests pass on your computer?

They, currently, do not even compile (Sorry, forgot to write that in the original post)

[dcc32 Error] mormot.db.raw.sqlite3.static.pas(1089): E2065 Unsatisfied forward or external declaration: 'sqlite3_progress_handler'

1. You need to download the latest static from https://github.com/synopse/mORMot2/rele … ite.3.34.1

2. TExecutable is not serializable for sure.
It was never meant to.
There is an embedded class field - TFileVersion - which prevents JSON Serialization.

I thought, I did :-o Only unpacked, but forgot to move...

My bad, but would have been cool to use directly for mustache ;-)

Thanks,
