I can confirm the bug with a build from
commit d6e93146b9f25e914373caeced7314237cc53e2f
(Don't remember which optimizing-option I used, though)
gdb says
Program received signal SIGSEGV, Segmentation fault.
0x00000000004ae5ab in Grob::get_offset (a=X_AXIS, this=0x0) at
/home/hermann/lilypond-git/lily/grob.cc:401
401 if (dim_cache_[a].offset_)
complete output from
(gdb) bt
attached.
