When I compile the following code with optimization flags (O1, O2, O3, Os) I
get compilation errors. If the code is compiled without optimizations (-g, -O0)
then everything is ok.
Error.cpp :
#include <libintl.h>
#define _(x) gettext(x)
typedef struct
{
int code;
const char* p_str;
} ErrorStr;
static ErrorStr g_errorStrTab[] =
{
{ 1, _("Success") },
{ 2, _("Invalid error code") },
{ 3, _("Invalid argument") },
{ 4, _("Convertion error") }
};
The platform is : Debian 2.2 Potato, glibc 2.1.3
The output of "gcc -v -save-temps -Os -c Error.cpp" is :
