I've noticed that, but at the time the bug has been introduced I
didn't find a solution too.

Looks like something goes wrong with the regexp engine introduced in Erlang 20.
We don't see consistent FTBFS until version 21.0, but it's only
because re:split/3
hasn't been used during Erlang builds. If you look at YAWS build logs
for example
(see [1]), you'll see that it started to fail on hppa just at the time
Erlang 20 appears.

I'll look into this, but I can't promise that it'll be soon. The hppa
architecture has
pretty low priority now, sorry.
