Crash in QQmlPropertyCacheAliasCreator<QV4::ExecutableCompilationUnit>::propertyDataForAlias ¿QML disk cache?

Note: Doesn't crash neither with Qt 6.4.2 nor with 6.6.0-beta4

I've tried both macos and linux and crashes on both.

The attached code crashes when run twice with the qml tool (doesn't crash if QML_DISABLE_DISK_CACHE=1 )

Backtrace:

• thread #6, name = 'QQmlThread', stop reason = EXC_BAD_ACCESS (code=1, address=0x10)
