Bug 9912 – Wrong codegen when using tuple over member variable in more than one method

GDC bug report: http://bugzilla.gdcproject.org/show_bug.cgi?id=49 LDC bug report: https://github.com/ldc-developers/ldc/issues/266 Minimal testcase: --- template Tuple(Stuff ...) { alias Stuff Tuple; } struct S { int i; alias Tuple!i t; void a() { auto x = t; } void b() { auto x = t; } } --- Causes an ICE in gdc and ldc because the dotvar expression 'this.i' is cached and re-used when building the tuple expression in both methods 'a' and 'b'. Meaning that both uses of 'this' is given the parent context of method 'a'. This is a problem when you try to access the 'this' parameter of 'a' from the function 'b'... Oops, you can't do that! Problem is in the D frontend, and should be fixed.
