The problem is really in Emacs's hacky implementation: when 'omake' is included in compilation-error-regexp-alist, many other regexps are rewritten in a way that makes them potentially slower. This is why it's not an ideal feature to have enabled by default. I'm okay with disabling 'omake' if we have nowhere else to ask. Thanks.

That's just a reputation. In reality, maybe its constant is lower than that of Emacs's regexp matcher, and maybe it implements a few more optimisations, but it suffers from the same explosion as Emacs's regexp matcher with regexps like the one under discussions (i.e. when Emacs's regexps are slow, it's because of the basty complexity introduced by backtracking and Perl's regexps do backtracking more or less as much as Emacs's).
