3482 – ICE(template.c:4017): instantiating invalid tuple template. D1 only.

The following (invalid) code produces an ICE:
void foo(T...)() {
 return "";
}
void main() {
 foo!(int, char)();
}
dmd: template.c:4017: Identifier* TemplateInstance::genIdent(): Assertion `0' failed.
The 'return "";' is invalid code, because it's inside a function with void as return type. (That's a recent change to dmd.) Apparently, instead of printing a proper error message, something goes wrong.
Interestingly, the example above works when you change it to 'foo!(int)();', and dmd will print what looks like a proper error message.

This is a regression between 1.036 and 1.041. It's nothing to do with return values: any error inside a tuple template will do it:
void foo(T...)() {
 bug;
}
void main() {
 foo!(int, char)();
}
On DMD1.041, this produced:
Assertion failure: 'i < parameters->dim' on line 796 in file 'template.c'

I believe this is a duplicate of bugzilla #1144.

What? issue 1144 is marked as fixed, but this bug is triggered in the newest release, even if this is just the symptom of another known bug as Don said.
