Bug #: 56155
Summary: [C++0X] enumeration with fixed underlying type - enum
literals have wrong type
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: mib.bugzilla@gmail.com
For an enumeration whose underlying type is fixed, the values of the
enumeration are the values of the underlying type. gcc appears to be ignoring
the underlying type, as the value of E_ in this example is 4
gpp48 bug1.cpp -std=c++0x
bug1.cpp: In function âint main()â:
bug1.cpp:4:3: error: static assertion failed: E_ should be 1
static_assert( E_ == 1, "E_ should be 1");
^
enum e_ : unsigned char { Z_, E_=sizeof(Z_) };
#include <stdio.h>
int main(void) {
static_assert( E_ == 1, "E_ should be 1");
printf("z is %d e is %d\n", Z_, E_ ); // prints 4
printf("sizeof unsigned char is %d\n", sizeof(unsigned char)); // prints 1
printf("sizeof e_ is %d\n", sizeof(e_)); // prints 1
return 0;
}
