Bug:
Intellisense stops working properly

Possible root cause is a getJSDocTags:

[sheetalkamat]

@sandersn can you please take a look

[sandersn]

#24973 should have fixed this yesterday.

However, I can't get this assert to repro to confirm whether it's fixed. @mjbvz do you mind trying with a newer build of typescript? We don't have an up-to-date typescript@next, but I can update this issue when we fix that problem.

[mjbvz]

Thanks @sandersn. I just tested the latest build from master and no longer see that error but the problem still exists. There is now this debug failure followed by a huge navtree that seems to contain a cycle or something:

Err 358   [14:21:43.969] Exception on executing command delayed processing of request 54:

    Debug Failure. False expression.

    Error: Debug Failure. False expression.

Does this assert (and the previous assert) occur with a call to tsc? I guess that it should but I could be wrong.

[sandersn]

Also, the assert happens when merging module augmentations, which means that the program has (or the compiler thinks it has) syntax like declare module "foo" { ... } or declare global { ... }. This seems unlikely for a JS file -- maybe you have some typescript?

Upgraded to 3.0@201806016. Seems to have Fixed the assertion failures and errors but I still see this file causing problems

[sandersn]

What kind of problems?

[mjbvz]

Mainly that requests take a long to process, especially after any file edits
