--- Comment #4 from Mathias LANG <pro.mathias.lang at gmail.com> ---
Regarding the original report, it is indeed a lack of backreference support.
This will be fixed once
https://gcc.gnu.org/pipermail/gcc-patches/2020-April/543278.html is accepted.
In the meantime, nothing we can do.
Regarding Seb's backtrace, the non-demangled symbols are C++ symbols. That's
another issue entirely (there's an open PR for it) so closing this as FIXED
(since there's an upstream patch).
