Bug ID: 60125 Summary: defaulted constructor with throwing NSDMI still declared as noexcept Product: gcc Version: 4.9.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: harald at gigawatt dot nl struct S { int i = (throw 0, 0); S() = default; }; int main() { try { S(); } catch(int i) { return i; } } The constructor for S is marked noexcept, and as a result, the exception thrown from i's initialiser cannot be caught, and this program aborts. This seems to be exactly what the standard requires: [except.spec]p14 says that the noexcept specification depends only on the functions invoked by the constructor. However, I'm reporting it anyway at the request of Marc Glisse, who says it's worth reporting even if it's a bug in the standard (http://stackoverflow.com/a/21660078/743382).
