I want to press Enter on the following code in a *compilation-mode*
buffer:

*** ASSERTION FAILED AT (363/reflect.hh:
10)

(note that the above code should all be on one line) so that it causes
Emacs to visit 363/reflect.hh at line 10. I believe that I am
supposed to add to one of the following
alists:

compilation-error-regexp-alist-
alist
compilation-error-regexp-
alist

but I am unsure which and what do I add to recognise the above
regexp.
