PATCH: DMD2.028 on mytype.c line 1272, replace assert(deco); with:
if (!deco) {
error(loc, ".mangleof forward reference");
return new StringExp(loc, "ERROR", 5, 'c');
}

I was surprised to find that in most cases, this error doesn't appear -- seems
the compiler absorbs the error and retries in the next semantic pass, and then
the code works correctly. In other words, it completely fixes the bug in D2.
>From the line number, seems it's a different cause in D1.

Actually it's nothing to do with pragma(msg). It's the mangleof which is the
problem. Change it to .stringof and problem disappears.
template Templ(T) {
const char [] XXX = Type.mangleof;
alias T Type;
}
void main() {
Templ!(int).Type x; // instantiate
}
