Additional Context

About the issue

A 'Segmentation fault' error occurs when trying to initialize a SQLite database via TypeORM within a Jest test file.

More especifically, it appears the value for 'entities' property in DataSource's constructor is related to the error. If an array containing a directory path is provided as value, error will surface. Otherwise, if an array containing an entity class is provided, test will execute successfully.

Note: Issue is present whether storing SQLite in-memory or disk file.

TypeORM: DataSource options

Workaround

Pass entity classes as argument, not directories, to DataSource's entities option.

import { MyEntity } from "./entities/MyEntity.ts";
// ...
- entities: ["entities/*.ts"],
+ entities: [MyEntity]
