@patrickkh7788 I have added a d.init.safeMode option that you can enable in VSCode. It disables processing multiple requests at the same time. I will add debugging info in DLS to see file names and lines in errors.

LaurentTreguier commented 5 years ago

Actually, I have an idea: some programs crash in release mode when using dmd -inline. Maybe disabling inlining could solve the problem.

LaurentTreguier commented 5 years ago

Starting from v0.21.2, DLS is compiled without inlining and without executable compression. Maybe one of those can solve the problem.

This looks like #25, and could perhaps be fixed by 656926b4ddd2ae2b521293f36088cc73742dfbb1
