It's the second multidefine segfaulting. It does not seem to happen
without '-r'.
Thanks for the report! Should be fixed in the latest git, please try.
You should get an error message saying "empty block" instead of a
segfault. Your script is a misuse of multidefine ("$msg" expands to
two words, so the second invocation of multidefine doesn't understand
what's going on), but that misuse wasn't properly caught.
Please give me a name (real if possible, else nickname) and e-mail
address
you wish to be credited with for the bug-report.
