Package: clang
Version: 1:3.0-6.2
Severity: minor
clang issues a warning when GCC's self-initialization trick as
described on http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36296#c3
is used. This is a bug a clang claims GNUC compatibility. See the
following testcase.
int foo (void);
void bar (int);
void f (void)
{
int init = 0;
#if defined(__GNUC__)
int x = x;
#else
int x;
#endif
while (1)
{
if (init == 0)
{
x = foo ();
init = 2;
}
bar (x);
}
}
Here, GCC's trick is necessary to avoid a warning with GCC. This
is protected with the "#if defined(__GNUC__)". Unfortunately clang
defines __GNUC__ and doesn't support this trick, which has the
effect to issue a warning instead of avoiding one.
