Forum:Backtrace limit exceeded during parsing!

Here's an error message that's new to me. Appeared at the top of the screen, repeated, after I entered a short name in the "create person page" form:

Semantic Forms error: backtrace limit exceeded during parsing! Please increase the value of pcre.backtrack-limit in the PHP settings.

Do we have a new problem?
