           Version: 4.8.0

          Severity: normal
          Priority: P3
         Component: go

log libgo test regressed again, probaby when libgo switched to libbacktrace. As
instructed in PR52583, I am opening a new PR for this.

For some reason _Unwind_Backtrace does not unwind after
backtrace_full/backtrace.c. This is problem in alpha unwinder.

If libbacktrace is compiled with -fasynchronous-unwind-tables, then btest works
OK. Also, when libbacktrace is compiled with this flag, log and runtime/pprof
does not fail anymore.
