Here are the times, in seconds, for executing compilation-parse-errors
far down a large compile buffer (5000 lines, or about 440 KiB),
with and without omake present in compilation-error-regexp-alist:

omake
present    absent
30.3        3.2     Standard code
 6.5        3.2     repaired regexp (escaped ^)
 3.2        3.2     COND expression removed

In the last case, the entire COND surrounding the faulty regexp was
edited out.
