Hi, we've started seeing compilation errors with our modularized build after
this commit. The errors say `'SomeType' has different definitions in different
modules`, but then point to the same definition that comes from the same
textual header included into two modules.
The setup (which I couldn't completely isolate yet) is roughly similar to this
(hopefully, I didn't miss any important parts):
Textual header p.h:
#include <type_traits>
#include "protobuf/generated_enum_util.h"
...
template <typename T,
typename =
typename std::enable_if<proto2::is_proto_enum<T>::value>::type>
class SomeType : E<S<T>> {
...
};
Textual header a.h:
#include <type_traits>
#include "protobuf/generated_enum_util.h"
namespace q {
template <typename T,
typename std::enable_if<::proto2::is_proto_enum<T>::value>::type>
class X {};
}
#include "p.h"
Textual header b.h:
// ...
// something likely unrelated
// ...
#include "p.h"
Module C, c.h:
#include "a.h"
#include "b.h"
