--- Comment #5 from Christian Hergert <chergert at redhat dot com> --- Created attachment 54985 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54985&action=edit First level of stack traces with g++ This shows stack traces when the only change was compiling harfbuzz with g++ instead of clang++. Much of the unwinding done by the kernel becomes corrupted and shallow as you can see by lots of functions which have no business being called before `_start` or `__GI__clone3` are getting called.
