--- Comment #7 from Jonathan Lebon <jlebon at redhat dot com> ---
I've updated the prologue searching algorithm so that we now pick up both
prologue_end markers (which clang emits) and 0-line advances (which GCC emits).
All the issues in comment 6 are now resolved, as well as the original
cast-scope testcase.
I also tested and tweaked it to work on older kernels/gccs (or at least to not
be less wrong than we were before). In some cases, we do even better there as
well!
