Bug 1401 – Multiple inheritance of abstract template classes lead to segmentation fault.

The following code using an abstract template class and multiple inheritance produces a segmentation fault. --- module mytest; import std.stdio; interface A(T) { C!(T) func(); size_t f(); } abstract class B(T): A!(T) { } interface C(T): A!(T) { } class D: B!(int), C!(int) { size_t f() { return 42; } C!(int) func() { return this; } } void main() { A!(int) x = new D(); writefln("%d", x.f()); } --- When I compile this snippet with dmd 2.003 on my linux-box, I get a segmentation fault on the call "x.f()" in the last line. Furthermore, if I use an interface instead of an abstract class for B, everything is fine. Even if I just change the order of definition of 'func' and 'f' in A, i.e. interface A(T) { size_t f(); C!(T) func(); } everything works.

Works in D2.026.
