I expect that the compiler regardless of the location of the types
always gives me the same result, error message or warning
indeed :
# case integer before double :
union
{
uint64_tinteger ;
double real;
} ;
gives me error, about narrowing conversion :
prova.cpp:32:5: error: narrowing conversion of '3.3999e+0' from
'double' to 'uint64_t {aka long long unsigned int}' inside { } [-Wnarrowing]
t1 = { 1 ,"a",3.4 } ;
^
# case double before integer, compile without warning or error me :
union
{
double real;
uint64_tinteger ;
} ;
and about output gives me undefined behavior about integer
t1 = { 1 ,"a",3.4 } ;
std::cout << t1.real << "\n" ;
t1 = { 1 ,"a",2 } ;
std::cout << t1.integer << "\n" ;

however if it is a normal behavior of c++ or compiler, close it.

source code where error7bug is generated
as you see in example below, g++ -std=c++11 fails compiler code,
when i assign a default value to a parameter in a struct definition
( i've tested with visual studio 2017 and all works good)
issue has generated in standard vectoru push back member
because it can not recognize struct correclty

Created attachment 43376
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43376&action=edit
file to reproduce error
i use this flags to compile program below :
-Wall -Wextra -pedantic-errors -std=c++11
g++ gives me NO warning, indeed with
-Wall -Wextra -pedantic-errors -std=c++11 -O3
g++ emit right warning
in this example g++ emit correct warning only when is active optimisation level
(123), but not with optimisation 0 or in other way
#include
#include
#include
uint64_t StringToInteger ( std::string str, int _base )
{
uint64_t n;
try
{
n = std::stoull ( str,nullptr,_base );
}
catch ( std::invalid_argument )
{
std::cout << "error" ;
}
return n ;
}
int main ( void )
{
std::cout << StringToInteger ( "123",10 ) ;
return 0 ;
}
in this other example
#include
#include
#include
uint64_t StringToInteger ( std::string str, int _base )
{
uint64_t n;
return n ;
}
int main ( void )
{
std::cout << StringToInteger ( "123",10 ) ;
return 0 ;
}
g++ emit warning ! with or without optimisation flags, rightly !
