@import causing process to hang

[xzyfer]

The following relative @import causes the process to hang iif a load path of . is given

// /tmp/index.scss
@import "../does-not-exist";

If the load path is omitted, an absolute path or something like subdir/.. the file executes and returns the expected error.

Error: File to import not found or unreadable: does-not-exist
       Parent style sheet: /tmp/index.scss
        on line 1 of index.scss
>> @import "../does-not-exist";
