Implement --enable-sanitizers[=sanitizers]
Similar to debugging with Valgrind, it's very useful to enable -fsanitize= switches to catch bugs at runtime. $ ./configure Result: no sanitizer enabled $ ./configure --enable-sanitizers Result: -fsanitize=address,undefined $ ./configure --enable-sanitizers=address,thread,undefined Result: -fsanitize=address,thread,undefined $ ./configure --enable-sanitizers=undefined Result: -fsanitize=undefined
