Follow-up Comment #2:
Thanks for the useful report, including reproduction instructions that worked
out of the box. The code is indeed calling memcpy(dest, NULL, 0) which works
on all known libc implementations, but where the sanitizer is indeed correct
that NULL is not a pointer to a valid object (even if we won't be copying from
it). It is easy enough to work around, so I'll post a patch along those
lines.
