The problem is now fixed upstream libmagic code repository
but we'll have to wait for file-5.25 release.

I've extracted official code fix from its repository, apply as following:

fetch http://www.grosbein.net/file/patch-regexmax.diff
cd /usr/src
patch < /path/to/patch-regexmax.diff
cd lib/libmagic
make obj depend && make all install
