Yes, allow_non_integral_constant_expression_p should always be true in
C++11.
Ah, good (sorry about the badly formatted code, by the way). Now, if I
apply the patchlet below, I get this error for template/nontype13.C:
nontype13.C:14:5: error: could not convert template argument
‘((Dummy<int>*)this)->Dummy<T>::evil<int>’ to ‘bool’
compared to the current:
nontype13.C:14:5: error: ‘void Dummy<T>::evil() [with T = int]’ cannot
appear in a constant-expression
Seems some sort of diagnostic quality regression...
By the way, before receiving your feedback, I was also wondering if the
tsubst_expr calls for STATIC_ASSERT should really pass true as
integral_constant_expression_p...
Paolo.
