You are missing .eh_frame CFI. Without that backtraces
will be unreliable. Make sure that gcc for riscv64 has
-fasynchronous-unwind-tables on by default and these
failures should disappear. It is the default on Fedora
riscv64 and there we see zero-fail.
Apart from that you might want to make sure your glibc has
the following patch:
