/share/toolchains/riscv/lib/gcc/riscv64-unknown-linux-gnu/8.2.0/../../../../riscv64-unknown-linux-gnu/bin/ld:
final link failed: Symbol needs debug section which does not exist
collect2: error: ld returned 1 exit status
Workaround: using "-O0" makes the linking procedure happy.
$ riscv64-unknown-linux-gnu-g++ -O0 riscv_cpp_test.c
