Package: gcc-4.4
Version: 4.4.4-8
Severity: important
Running the following code with gcc-4.4 will print "A" even though the
value of bar in is actually 64 at runtime.
The correct behaviour is surely to print "invalid bar"?
As you can see from the code, adding a default case changes the
behaviour which I find even more strange.
Looking at the asm it seems that gcc is making as assumsion that
bar must be in the valid range of the enum.
This problem does not exist in gcc-4.3
#include <stdio.h>
enum foo
{
A = 0,
B = 1
};
int main()
{
foo bar = (foo)64;
switch (bar)
{
case A: printf("A\n"); return 0;
case B: printf("B\n"); return 0;
// uncomment this line to stop A being printed!
//default: break;
}
printf("invalid bar\n");
return 1;
}
