This is a followup from Bug #24358, since that thread filled up with
messages about the crash in 25.1, so I'm opening a new bug for the wrong
regex stack overflow check (this affects only the master branch).

To reproduce the error run (re-search-forward ".*\\(\n.*\\)*" nil t) in
a buffer with contents of the attached bug-24358-regex-max-specpdl.txt.
