digitalmars.D.bugs - DMD crash with "= .dup" as an inout parameter

Yes I know this is a silly naughty thing to do in the first place, but the
compiler still 
shouldn't crash.  Here's a minimal program that will cause the event.

# 1# int main (char[][] args) {
# 2#   int[] foo,
# 3#         bar;
# 4#
# 5#   func(bar = foo.dup);
# 6#   return 0;
# 7# }
# 8#
# 9# void func(inout int[] x) {
#10# }

It issues this error:
## bug.d(5): bar = _adDup(foo,4) is not an lvalue

Then crashes and burns.  I'm using DMD 0.128 on Windows.
