Deno crashes (not a rust panic), when debugging a specific piece of code

[TopchetoEU]

When trying to debug the following code:

export class MyClass {
    public constructor(public member: number) { }
    public static readonly static = null;
}

new MyClass(10);

and try to step into the constructor on the last line, Deno crashes with the following error:

#
# Fatal error in , line 0
# Check failed: IsStringSet(*block_list).
#
#
#
#FailureMessage Object: 0x7ffc7741c6f0

I believe this has to do with either wrong interpretation or wrongly generated source maps.

Workaround:
Instead of using static fields, put them in a namespace with the same name:

export class MyClass {
    public constructor(public member: number) { }
}
export namepsace MyClass {
    export const _static = null;
}
