Yes, it looks as if this is caused by one of Zack's recent changes.
We have:
#0 0x400000000035ee3c in copy_rtx (orig=0x0) at ../../gcc/gcc/rtl.c:377
#1 0x40000000002f869c in emit_libcall_block (insns=0x800003fffed1f550,
target=0x800003fffed20600, result=0x800003fffed1f2d0, equiv=0x0)
at ../../gcc/gcc/optabs.c:3397
#2 0x40000000002f9430 in emit_cmp_and_jump_insns (x=0x800003fffed3bfa0,
y=0x800003fffeff2768, comparison=NE, size=0x72, mode=TFmode, unsignedp=0,
label=0x800003fffed3bf50) at ../../gcc/gcc/optabs.c:3946
emit_libcall_block is called with equiv=0 when optimize is 0. We end
up trying to copy a NULL_RTX at optabs.c:3397.
