void foo(bool b)
{
switch ((unsigned int)b) {
case 1:
case 2: ;
}
}
% g++ test.cc
test.cc: In function void foo(bool):
test.cc:6: error: duplicate case value
test.cc:5: error: previously used here
The bug only appears with casts to (unsigned int) or wider; casts to (int),
(unsigned short), etc., work as expected.
Reproduces with GCC versions 4.2.4 and 4.3.2.
