Here's the C code:

type_t *res;
type_t *x = min_of_x( data, len);
type_t *y =

I was wrong in comment #9. The bug and the proposed fix are ok in comment #7.
While writing some tests for error I discovered yet another bug in UTF-8
decoding. See the example:

I've made a copy-paste error (I cant change the submitted bug), after B) it

I forgot to add Bill Schmidt's name to the ChangeLog entry. He helped with the
initial conversion to use the DF framework. I will add his name in my copy of
the patch.

Nice analysis. Personally I dislike when you get different results from

The following patch adds streaming of edge goto_locus (both LOCATION_LOCUS
and LOCATION_BLOCK from it), the PR shows a testcase (inappropriate for
