<pre>Since SVN r362119, "Add Attribute NoThrow as an Exception Specifier Type",
compiling Qt on MinGW fails with the following error:
This spec type is compatible with none.
UNREACHABLE executed at ../tools/clang/lib/Sema/SemaExceptionSpec.cpp:426!
This can be trivially reproduced with the following test snippet:
$ cat test.cpp
class Foo {
public:
__attribute__((nothrow)) void __attribute__((__stdcall__)) Bar();
};
void Foo::Bar() {
}
$ clang -target i686-w64-mingw32 -c test.cpp -std=c++17</pre>
