Comment #13 on issue 1732 by address@hidden: occasional segfault when compiling input/regression/midi/key-initial.ly
http://code.google.com/p/lilypond/issues/detail?id=1732 Looking through the code, it appears as follows to me:-) Grob::internal_set_property calls Grob::is_live (), which crashed in line 312 with the check
return scm_is_pair (immutable_property_alist_);-) So, it seems like the immutable_property_alist_ member is not initialized. -) All Grob constructors initialize that member from the passed argument (either Grob* or SCM props) -) So, my conclusion for now is that somewhere a grob (or some child class instance) is created with the Grob (SCM props) constructor, where the passed argument SCM props is some uninitialized value.
