[Bug #19028] Suppress GCC 12 `-Wuse-after-free` false warning
GCC 12 introduced a new warning flag `-Wuse-after-free`, however it
has a false positive at `realloc` when optimization is disabled, since
the memory requested for reallocation is guaranteed to not be touched.
This workaround is very unclear why the false warning is suppressed by
a statement-expression GCC extension.
