[Libguestfs] Rare nbdkit crash on RISC-V



This is quite rare, it happens perhaps one in 10 runs:

  qemu-img: Could not read file metadata: Input/output error
  nbdkit: nbdkit command was killed by signal 11
  ...
  FAIL test-sh-extents.sh (exit status: 4)

Full log and stack trace is attached.

systemd-coredump collects a core dump.  The stack trace seems to
indicate memory corruption.  On one run (not the one attached) I got
an error message from malloc, the exact text I forget, but it seemed
to indicate corruption in the glibc allocator.

It's a bit mysterious and quite surprising that it doesn't happen on
non-riscv64 platforms as far as I've seen.

Unfortunately there's no valgrind for RISC-V :-(

Still investigating ...

Rich.

glibc-2.32-4.fc33.riscv64
