Alex Richardson cbcfe28f9d libc/qsort: Don't allow interposing recursive calls ... This causes problems when using ASAN with a runtime older than 12.0 since the intercept does not expect qsort() to call itself using an interposable function call. This results in infinite recursion and stack exhaustion when a binary compiled with -fsanitize=address calls qsort. See also https://bugs.llvm.org/show_bug.cgi?id=46832 and https://reviews.llvm.org/D84509 (ASAN runtime patch). To prevent this problem, this patch uses a static helper function for the actual qsort() implementation. This prevents interposition and allows for direct calls. As a nice side-effect, we can also move the qsort_s checks to the top-level function and out of the recursive calls.
