Clang's reproducible crash files
Clang crashes when trying to compile a simple translation unit containing an
`import` statement.
How to reproduce:
$ cat math.mxx
#include <utility>
export module math;
export namespace math
{
template <typename... Ts>
decltype(auto) sum(Ts && ...values)
{
return (std::forward<Ts>(values) + ... + 0);
}
}
$ cat main.cpp
import math;
int main()
{
return math::sum(1, 2, 3);
}
$ clang++ -std=c++2a -fmodules-ts --precompile -x c++-module -o math.pcm
math.mxx
$ clang++ -std=c++2a -fmodules-ts -o math.pcm.o -c math.pcm
$ clang++ -std=c++2a -fmodules-ts -fmodule-file=math.pcm main.cpp
