Bug ID: 91261 Summary: noptr-new-declarator does not accept converted constant expressions Product: gcc Version: 8.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: smw at gcc dot gnu.org Target Milestone: --- The restrictions on the constant-expression of noptr-new-devlarators was changed from integral constant expressions in C++11 to converted constant expressions in C++14 [expr.new] 5.3.4/6. GCC rejects non-integral expressions with the message "error: expression in new-declarator must have integral or enumeration type". Reproducer follows. int main() { void* p26 = new int [1.0f][3]; } Confirmed in GCC 8.3, 9.1, and trunk.
