  Log Message:
  -----------
  [ubsan-minimal] Report the address of an error

This implements a FIXME in the runtime library and adds printing the
address at the end of the message as "by 0x123abc". The buffer for the
message is allocated on the stack in a handler, so the stack memory
consumption is slightly increased. No additional external dependencies
are added.
