[cxx-abi-dev] Itanium ABI fails to specify how to mangle lambdas

[Michael Wong]

Lambdas can appear in contexts where the ABI requires that the expression
be mangled.
Note that the lambdas below participate in SFINAE as far as I know.

template <typename T>
void foo(const int *, char (*)[sizeof(T) > 1 || [] { goto lab; for (;;)
lab: return T(); }] = 0) { }

template <typename T>
void foo(int *ptr, char (*)[sizeof(T) > 1 || [] { goto lab; decltype(ptr)
ptr; lab: return T(ptr); }] = 0) { }

int main() {
   foo<float>(static_cast<int *>(0));
}
