Comment #13 on issue 1732 by reinhold...@gmail.com: 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.
