Search Terms: excessive stack depth regression comparing types function lodash

Code

tsconfig.json:

{
    "compilerOptions": {
        "allowSyntheticDefaultImports": true,

        // Disable this and you get more information about the errors?
        "strictNullChecks": true
    }
}

package.json:

{
  "dependencies": {
    "@types/lodash": "4.14.129",
    "typescript": "3.6.2"
  }
}

main.ts:

import negate from 'lodash/negate';

Expected behavior:

Compiles

Actual behavior:

$ tsc
error TS2321: Excessive stack depth comparing types 'Function<?>' and 'Function<?>'.


Found 1 error.

This error doesn't give any helpful information for debugging.

Upgrading @types/lodash to the latest version (4.14.138 at time of writing) seems to fix the issue.

If we disable strictNullChecks, we get a bit more information about the error (for some reason?):

$ tsc
error TS2321: Excessive stack depth comparing types 'Function<?>' and 'Function<?>'.

node_modules/@types/lodash/ts3.1/common/common.d.ts:194:15 - error TS2589: Type instantiation is excessively deep and possibly infinite.

194     interface Object<T> extends LoDashImplicitWrapper<T> {
                  ~~~~~~


Found 2 errors.

This did not error in TS 3.5, so I think it's a regression?
