#2393 Segfault in connection with \markuplist

Can please somebody check this against being a regression?  In earlier versions, \markuplist was called \markuplines, please take this into account when checking.

2.15.32 on the same system but using \markuplist gives the same result.

Does this help?

Some.  If it also crashes in 2.12, this is not a critical regression.

I actually have no idea why something as simple as that would crash (does not seem all that new, either).

2.12.3 crashes,too

I'm on Linux 64-bit 10.04
Compiled with Frescobaldi

Code:
\version "2.12.3"
\markuplines \bold { \wordwrap-lines {  } }

Should be: I'm on Linux 64-bit Ubuntu 10.04

So this is not a regression.  That's good news for 2.16 release planning.  Still needs to get investigated.

#(display #{ \markuplist \bold { \wordwrap-lines {  } } #})
outputs
((#<procedure bold-markup (layout props arg)> (#<procedure wordwrap-lines-markup-list (layout props args)> ())))

I would assume that this is not a valid markup list.

Unwrapping the list leads to
\markup \bold { \wordwrap-lines { } }

as a test case.  This is accepted and leads to an error message in processing:

Parsing.../usr/local/share/lilypond/2.15.31/scm/define-markup-commands.scm:1118:6: In procedure ly:stencil-empty? in expression (remove ly:stencil-empty? stencils):
/usr/local/share/lilypond/2.15.31/scm/define-markup-commands.scm:1118:6: Wrong type argument in position 1 (expecting Stencil): (#<Stencil  >)

That seems to be the same problem: a markup list (or stencil list) where a markup is expected.

Also on 2.12.3 on Windows crashes too.
