However, this release segfaults a lot!
Hi Martin,
do you see this warning message about {{{warning: returning reference to
temporary}}}? I got that warnings when building on !OpenSolaris - see
below.

That sounds the sort of error which could result in segfaults.
I'm attaching a patch which gives much improved error checking.
