Edit:
A suggestion that takes no effort to implement, with the same effect and fits the question discussed here:
In the question template, there should be a suggestion,
If your program returns an error message, make it the title of your question.
When followed by the OP, it will trigger the suggested answers mechanism with (hopefully) decent accuracy. And will help Google to find this question when it's the first question regarding such an error.
There should be a dedicated input field for the error message. That will improve the process dramatically, as it will allow for a system that provides a correct list of suggested answers, not to mention other benefits like correct formatting, less discussion in the comments, better answers, etc.
This field obviously should be made non-required, and could be left empty.
