That should be doable, yes, but it might be a lot of work
and the patch is straightforward and appears correct.
For now I installed the patch into gnulib, here:
http://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=1997177209382391a38d061f234fe04c74b863da
so that GNU applications on non-glibc platforms
will get the fix.
Stanislav, if you find a short and reproducible
test case, please cc: it to bug-gnulib so that I can
add it to the gnulib test cases too.
Also, if you figure out what's causing sed to loop,
that'd be even better: quite possibly it's another bug
in the regex code, one that we should squash.
