I see you put this on the 4.5 branch as well, but I get with RTL checking:

/home/eric/gnat/gnat6_45/src/gcc/testsuite/g++.dg/debug/pr44178.C: In 
function 'B f4(int, int, int)':
/home/eric/gnat/gnat6_45/src/gcc/testsuite/g++.dg/debug/pr44178.C:39:1: 
internal compiler error: RTL check: expected elt 3 type 'B', have '0' (rtx 
barrier) in setup_insn_max_reg_pressure, at haifa-sched.c:1589
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
