--- Comment #1 from Jan Echternach <jan.echternach at de dot gbs.com> ---
I can confirm this bug in gcc 4.9 (Debian 4.9.2-10). A different example which
also produces wrong code (should return 0, but returns 1):
//#include <stdio.h>
int main ()
{
if (0)
#pragma GCC diagnostic ignored "-Wtype-limits"
{
//printf ("bug\n");
return 1;
}
//printf ("ok\n");
return 0;
}
And an example that fails to compile ("error: ‘else’ without a previous ‘if’"):
void foo (void)
{
if (0)
#pragma GCC diagnostic ignored "-Wtype-limits"
{}
else {}
}
