I just tried to compile package lilypond-2.6.5-2 from Suse Linux with a recent GNU C++ compiler version 4.2 snapshot 20060204.
The compiler snapshot said rm -f ./out/drum-note-performer.dep; DEPENDENCIES_OUTPUT="./out/drum-note-performer.dep ./out/drum-note-performer.o" /home/dcb/gnu/42-20060204/results/bin/g++ -g -O3 -Wall -fmessage-length=0 -c -O2 -g -fmessage-length=0 -D_FORTIFY_SOURCE=2 -DHAVE_CONFIG_H -DNDEBUG -DSTRING_UTILS_INLINED -Iinclude -I./out -I../flower/include -I../flower/./out -I../flower/include -I/usr/include/python2.4 -DNDEBUG -O2 -g -fmessage-length=0 -D_FORTIFY_SOURCE=2 -O2 -finline-functions -pipe -I/opt/gnome/include/pango-1.0 -I/usr/include/freetype2 -I/opt/gnome/include/glib-2.0 -I/opt/gnome/lib64/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/python2.4 -DNDEBUG -O2 -g -fmessage-length=0 -D_FORTIFY_SOURCE=2 -O2 -finline-functions -pipe -I/opt/gnome/include/pango-1.0 -I/usr/include/freetype2 -I/opt/gnome/include/glib-2.0 -I/opt/gnome/lib64/glib-2.0/include -I/usr/include/freetype2 -W -Wall -Wconversion -o out/drum-note-performer.o drum-note-performer.cc drum-note-performer.cc: In member function "virtual void Drum_note_performer::create_audio_elements()" drum-note-performer.cc:48: internal compiler error: in gimplify_var_or_parm_decl, at gimplify.c:1594Please submit a full bug report, with preprocessed source if appropriate.
