I run into DMD segmentation fault under linux and Mac OSX, not test windows
yet.


DMD v2.078.0-401-g716303a41-dirty DEBUG

Program received signal SIGSEGV, Segmentation fault.

!ClassDeclaration.exception.isBaseOf(cd, null) &&


The demangle symbol is: void
dmd.statementsem.catchSemantic(dmd.statement.Catch, dmd.dscope.Scope*) 


The code is rather big and I can not made it work with dustmite.
