Created an attachment (id=1048)
withoutstd

Here's a reduced version not importing phobos. Don't know if that helps.

Reduced test case, requires -inline:

bool decode(S)(ref int x) {
    return true;
}

bool front(A)() {
    int i = 0;
    return decode!(char)(i);
}

static assert( is(typeof({ front!(int)(); }())) );
static assert ( front!(int)());

Further reduced. Still requires -inline.

bool bug7043(S)(ref int x) {
    return true;
}

static assert( {
    int i = 0;
    return bug7043!(char)(i);
}() );
