The ICE seems to be when initialising the closure type's data member for an
object of reference type implicitly-captured by copy.
Slightly further reduced:
int
main()
{
int i = 10;
int& ir = i;
[=]
{
(void) ir;
}();
}
(In reply to comment #1)

That's invalid:
"If a lambda-capture includes a capture-default that is =, the lambda-capture
shall not contain this and each identifier it contains shall be preceded by &."
