Comment #6 on issue 1336 by n.puttock: skipTypesetting segfaults when set
during a skipBars-induced MultiMeasureRest spanner
http://code.google.com/p/lilypond/issues/detail?id=1336
A bit more data: in the crash-case, grob-property.cc
internal_get_property() calls internal_get_property_data () with
minimum-X-extent, and receives the answer of
()
Are you sure that's the root cause though? It looks to me like the
MultiMeasureRest has invalid bounds when cloned, so the cloned object is
NULL when the MultiMeasureRestNumber is aligned (the parent object no
longer exists).
I can see several workarounds for this, but ideally the
MutiMeasureRestNumber would be suicided if the parent object's invalid.
Unfortunately, it doesn't look as if this is possible in the engraver (at
that point the original rest appears to have valid bounds).
