We currently get
/tmp/junk2.ly:1:2: warning: barcheck failed at: 1/2
{
R2 }
Preprocessing graphical objects...
programming error: Multi_measure_rest::get_rods (): I am not spanned!
continuing, cross fingers
programming error: Object is not a markup.
continuing, cross fingers
This object should be a markup: ()
programming error: Multi_measure_rest::get_rods (): I am not spanned!
continuing, cross fingers
Instead, the message better be either
Warning: multimeasure rest fails bar check
(in case that its length _is_ a full bar multiple)
or
Error: multimeasure rest size not a multiple of bar size
(in case that it could not work out anyway).
In case of a warning, error recovery needs to result in something
reasonably sensible. If that is not feasible, one needs to create an
error instead.
A warning implies that Lilypond is going to do continue with reasonable
results.

Hi!
Please, can you tell what lilypond should output in this case?
Thanks!

Incomprehensible error messages count as bugs.

use R\breve-\fermataMarkup (see the docs about full measure rests).

R2 does not fill the measure that's why the MultiMeasureRest complains.
No LilyPond bugs as far as I can tell.

programming errors: "Object is not a markup." and "I am not spanned!"
L.S.,
For the following file
\version "2.12.4"
{ R\breve\fermata }
lilypond reports the following "programming error":
$ lilypond bug.ly
GNU LilyPond 2.12.4
Processing `bug.ly'
Parsing...
Interpreting music...
Preprocessing graphical objects...
programming error: Object is not a markup.
continuing, cross fingers
This object should be a markup: ()
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...
programming error: cannot align on self: empty element
continuing, cross fingers
Layout output to `bug.ps'...
Converting to `./bug.pdf'...
$
Even more alarming-looking,
\version "2.12.4"
{ R2 }
results in a (correct) "barcheck failed" warning, but also in an "I am not
spanned!" error:
$ lilypond bug2.ly
GNU LilyPond 2.12.4
Processing `bug2.ly'
Parsing...
Interpreting music...
bug2.ly:2:2: warning: barcheck failed at: 1/2
{
R2 }
Preprocessing graphical objects...
programming error: Multi_measure_rest::get_rods (): I am not spanned!
continuing, cross fingers
programming error: Object is not a markup.
continuing, cross fingers
This object should be a markup: ()
