Maybe one can work around it by constructing the regexp differently:
instead of allowing any character sequence between "/*" and "*/", one
restricts the possible sequences, with the following idea:

- any sequence of [^*] is allowed
- a * followed by [^/] is allowed

The above two can be repeated.

I think that avoids backtracking.
A preposition is not a good thing to end a sentence with.
