On compiling the files in the below zip file (with unittesting), I get

dmd: statement.c:138: virtual int Statement::blockExit(): Assertion `0' failed.

There's a fair deal of code in there, but I believe its coming from
TestRecords, for anyone bothering to whittle this one down.

I don't think it's fair for Walter or Don to debug your code. So I suggest you
to first of all merge all that code in a single module, then start removing
parts and keep that ICE, until you reach to a short enough program to post here
again.

I think it's fair for Walter or Don to debug their code.

Anyways, I lied about TestRecords.

This is as small as I care to get it:

public int blitvisit()() {
    foreach(k; s.tupleof){
            mixin(BlitX!());
    }
}

void main(){
    blitvisit!()();
}

If you post several modules here then you are asking people to debug your code.

Your last code doesn't show the ICE, it just shows:
test.d(2): Error: undefined identifier s

This is D1-only. Reduced test case:

void bug4125() {
    foreach(k; s){
        mixin("");
    }
}
--------
test0.d(384): Error: undefined identifier s
test0.d(384): Error: cannot infer type for k
Statement::blockExit(00C17914)
mixin("");

Passed in 1.030, ICE in 1.034.
