--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I've also seen this behavior (throwing away useful data) with PR78063. So
fixing this would also help PR78063 for the cases ASAN backtraces are affected
(I needed to adjust the testsuite outcome for early LTO debug).
Confirmed.
Not sure if this is part of upstream asan (so should be reported there) or if
this is part of GCC local changes.
