From: Thomas Frauendorfer | Miray Software <[email protected]> The commit c68b7d236 (commands/test: Stack overflow due to unlimited recursion depth) added recursion depth tests to the test command. But in the error case it decrements the pointer to the depth value instead of the value itself. Fix it.
