At least the following are likely to be broken (since they are quite  
similar and I get already 2 of them bad).

lily/font-size-engraver.cc:  gi.grob ()->set_property ("font-size",  
scm_from_dou
lily/ligature-engraver.cc:        info.grob ()->set_property ("stencil",  
brew_li
lily/new-fingering-engraver.cc:          inf.grob ()->set_property  
("style", ly_
lily/pitch-squash-engraver.cc:    i.grob ()->set_property  
("staff-position", new
lily/tab-staff-symbol-engraver.cc:    gi.grob ()->set_property  
("line-count", sc
lily/tweak-engraver.cc:          info.grob ()->set_property (scm_caar (s),  
scm_c

And then I get something like
Preprocessing graphical  
objects.../usr/local/tmp/lilypond/out/share/lilypond/current/scm/output-lib.scm:139:9:  
In procedure ly:event-property in expression (ly:event-property  
(event-cause grob) (quote duration)):
/usr/local/tmp/lilypond/out/share/lilypond/current/scm/output-lib.scm:139:9:  
Wrong  
type argument in position 1 (expecting Stream_event): #f

g++-4.6.1 is a bottomless pit, period.  I don't see that anything but  
workaround options makes sense here.
