With latest clang 13.0.0 we get
|
||
|
|
|
||
|
|
../ui/clipboard.c:47:34: error: variable 'old' set but not used [-Werror,-Wunused-but-set-variable]
|
||
|
|
g_autoptr(QemuClipboardInfo) old = NULL;
|
||
|
|
^
|
||
|
|
|
||
|
|
The compiler can't tell that we only declared this variable in
|
||
|
|
order to get the side effect of free'ing it when out of scope.
|
||
|
|
|
||
|
|
This pattern is a little dubious for a use of g_autoptr, so
|
||
|
|
rewrite the code to avoid it.
