The warning available in previous versions of gcc (at least until gcc 3.3)
'unreachable code at beginning of switch statement' is not reported anymore.
This behavior hides programming errors. When compiling this code sample with
'c++ -Wall test.cpp':
int main()
{
int a;
switch(1)
{
a = 1;
break;
default:
break;
}
return 0;
}
No warning is reported. Older versions of gcc issue a warning here. Using
additional switch-related warnings like -Wswitch does not change anything.
