<pre>This test case:
template<typename = int>
void f (const char* a =
([](int = [] {
static int i; return 42;
}()) {
static int i; return "";
}()));
void g() {
f();
}
compiles with clang 10.0. See <a href="https://godbolt.org/z/eEbW6Gnjf">https://godbolt.org/z/eEbW6Gnjf</a>
and fails with an assertion. See <a href="https://godbolt.org/z/41GbzPa4Y">https://godbolt.org/z/41GbzPa4Y</a>
Assertion failed: (isGenericMethod || Ty->isVariablyModifiedType() ||
Ty.getNonReferenceType()->isObjCRetainableType() || getContext()
.getCanonicalType(Ty.getNonReferenceType()) .getTypePtr() ==
getContext().getCanonicalType((*Arg)->getType()).getTypePtr()) && "type
mismatch in call argument!", file CGCall.cpp, line 4072</pre>
