Error description
After a complex IF statement, a thrown exception causes the program to crash after the exception handling __DoThrowV6() call. The stacktrace points to a basic_string destructor: === STACK TRACE === statics.std::_UseFacet<std::num_put<wchar_t,std::ostreambuf_iter ator<wchar_t,std::char_traits<wchar_t> > >,1>::_Use(const std::locale&,const std::locale::facet*&,const std::locale::facet*).std::basic_string<char,std::char_traits<cha r>,std::allocator<char> >::_Tidy(bool)(??, ??) at 0xd3ec93a8 std::basic_string<char,std::char_traits<char>,std::allocator<cha r> >::?basic_string()(??, ??) at 0xd3ec91a0 test.std::basic_string<char,std::char_traits<char>,std::allocato r<char> >::__dftdt()(0x2ff21590) at 0x10001058 invokedtr.__Invoke__Destructor() at 0xd14d4be4 __DoThrowV6() at 0xd14d6b78 test(Nry&)(0x2ff21690) at 0x10000d30 main(0x1, 0x2ff21730) at 0x10000e08
Local fix
None. Occurance of the issue is sensitive to minor code logic changes.
Problem summary
PROBLEM DESCRIPTION: The compiler is removing certain temporary values that have exception entries in them, causing incorrect behaviour. USERS AFFECTED: Users with compound conditional statements with copy constructors in them.
Problem conclusion
The compiler now prevents the exception entries from being removed by preventing variable replacement during temporary elimination. The fix has been implemented.
