For the second testcase (ICE in varasm.c) Clang says:
/home/jcelerier/i-score/base/plugins/iscore-plugin-scenario/source/Process/ScenarioModel.cpp:57:46:
error: constexpr variable 'staticMetaObject' must be initialized by a constant
expression
constexpr const QMetaObject NotifyingMap<T>::staticMetaObject{
^ ~
/home/jcelerier/i-score/base/plugins/iscore-plugin-scenario/source/Process/ScenarioModel.cpp:57:46:
note: pointer to subobject of temporary is not a constant expression
/home/jcelerier/i-score/base/plugins/iscore-plugin-scenario/source/Process/ScenarioModel.cpp:59:22:
note: temporary created here
strdata_t<T>{}.data,
Thus, also ICE on invalid, and it does not reproduce on trunk (but looks like
it turned into accepts-invalid). The first ICE does reproduce.
I'll post a reduced testcase shortly.
