struct Foo { int x; } void main() { Foo(5).x++; } DMD 2.059beta gives me: Internal error: backend\cgcs.c 517

This has the same cause as issue 3008, the increment should be rejected during semantic as it is trying to operate on an rvalue, but isn't because DotVarExp::modifiableLvalue only checks that that _type_ is modifiable.
