Yep, this is the case, it includes pre-compiled regular expressions and
these appear to be incompatible between versions of pcre.

We've come up with a better solution, which is to add dependencies to
the apertium package, and then make the apertium package depend on a
particular version of pcre3. It's safer this way, as I can't find out
anything about compatibility of precompiled regular expressions in pcre
between versions, so better to assume they aren't.
