Bug 782 – Dmd crash with template class, alias, inheritance and severals files

Here is the code:(2 files) [test.d] import test2; abstract class UpperClass { } [test2.d] import test; abstract class MiddleClass : UpperClass { } class Generic(T) : MiddleClass { T m_value=0; } alias Generic!(byte) GenericByte; [/test2.d] If I compile with: dmd test.d test2.d Then it crashes. Some important facts about this issue: -if everything is coded is one file, dmd compiles well -if I import test2 AFTER the declaration of UpperClass and NOT BEFORE, dmd compiles well -if I remove "alias Generic!(byte) GenericByte;", dmd compiles well -if I change "T m_value=0;" to "T m_value;", dmd compiles well -if MiddleClass does not inherite from UpperClass or Generic inherite from MiddleClass, dmd compiles well When I say it compiles well of course, I mean without crashing

For now, I can reduce this to a compile time forward reference error rather than a seg fault.

Works fine with DMD 1.004.
