Summary: ICE on struct template semantic with missing
identifier and recursive instantiations
Product: D
Version: D2
Platform: All
OS/Version: All
Status: NEW
Severity: normal

struct Foo(int x) {
auto bar() {
auto a = is(Foo!3) == is(Foo!3);
Nonexistent();
}
}
void main( ) {
Foo!2 a;
}
The above program crashes the compiler with this message:
assert struct.c(791) type->ty != Tstruct || ((TypeStruct *)type)->sym == this
(that's in StructDeclaration::semantic, btw)
Changing the template instantiations inside bar() to equal that in main()
causes the problem to disappear. Thus it seems the problem is caused by a
template that's not fully analyzed yet.
Removing one of the isExpressions fixes the problem. Using __traits(compiles,
{Foo!3 f;}) in place of (one or both) the isExpressions causes the same
problem.
Removing the call to Nonexistent() fixes the problem.
