In short then, I propose applying 0001-0006. I'm not quite sure if we should back-patch, or just be content to fix this in HEAD. But there's definitely an argument that this has been broken since we added phrase search (in 9.6) and deserves to be back-patched.
Thanks for fixing this.
I am getting a compiler warning, both with and without --enable-cassert.
wparser_def.c: In function 'prsd_headline': wparser_def.c:2530:2: warning: 'pose' may be used uninitialized in this function [-Wmaybe-uninitialized] mark_fragment(prs, highlightall, bestb, beste); ^ wparser_def.c:2384:6: note: 'pose' was declared here int pose,
It makes no sense to me that pose could be used uninitialized on a line that doesn't use pose at all, so maybe it is a compiler bug or something.
