.Valgrind rebased to version 3.16.0 The Valgrind executable code analysis tool has been updated to version 3.16.0, which provides a number of bug fixes and enhancements over the previous version: * It is now possible to dynamically change the value of many command-line options while your program is running under Valgrind: through `vgdb`, through a `gdb` connected to the Valgrind gdbserver, or through program client requests. To get a list of dynamically changeable options, run the `valgrind --help-dyn-options` command. * For the Cachegrind (`cg_annotate`) and Callgrind (`callgrind_annotate`) tools the `--auto` and `--show-percs` options now default to `yes`. * The Memcheck tool produces fewer false positive errors on optimized code. In particular, Memcheck now better handles the case when the compiler transformed an `A && B` check into `B && A`, where `B` could be undefined and `A` was false. Memcheck also better handles integer equality checks and non-equality checks on partially defined values. * The experimental Stack and Global Array Checking tool (`exp-sgcheck`) has been removed. An alternative for detecting stack and global array overruns is using the AddressSanitizer (ASAN) facility of GCC, which requires you to rebuild your code with the `-fsanitize=address` option.
