Maybe VIR_FREE should be changed to something like
-# define VIR_FREE(ptr) virFree(&(ptr))
+# define VIR_FREE(ptr) \
+ do { void *check_type = (ptr); virFree(&(check_type)); } while (0)
so that the compiler can warn about such issues?
With this change, I get
remote.c: In function 'remoteDispatchListInterfaces':
remote.c:3978:33: warning: initialization makes pointer from integer
without a cast [enabled by default]
I also get more warnings about casting from const to non-const, this can
be avoided by making check_type const void *, but maybe these warnings
indicate that something that shouldn't be freed is freed.
