This is fixed in DMD2.028 but not in 1.042.

Assertion failure: 'i < parameters->dim' on line 806 in file 'template.c'

This is the test case which is failing in dstress:

char[] testHelper(A ...)(){
   char[] result;
         foreach(t; a){
             result ~= "int " ~ t ~ ";\n";
         }
         return result;
}

     int main(){
         mixin( testHelper!( "hello", "world" )() );
         return 0;
     }

Note that in the foreach(), it's 'a' instead of 'A'. So it's a bad test, which
is actually an instance of bug 2229 (which I've just patched). The bug here was
indeed fixed in 1.014.

The dstress test is failing again in dmd 1051:
dmd: template.c:4017: Identifier* TemplateInstance::genIdent(): Assertion `0'
failed.

That DStress case is correct, it's in nocompile/, so shouldn't compile.

Yes, but it's testing bug 2229, not the one which was originally reported here.
I'm closing this one, and re-opening the other.
BTW it's not a regression. Bug 2229 was never fixed properly.
