Sometimes is better to use gcc fsanitize family.

-fsanitize=address

Enable AddressSanitizer, a fast memory error detector. Memory access
instructions are instrumented to detect out-of-bounds and use-after-free
bugs. The option enables -fsanitize-address-use-after-scope. See
https://github.com/google/sanitizers/wiki/AddressSanitizer for more
details. The run-time behavior can be influenced using the ASAN_OPTIONS
environment variable. When set to help=1, the available options are shown
at startup of the instrumented program. See
https://github.com/google/sanitizers/wiki/AddressSanitizerFlags#run-time-flags
for a list of supported options. The option cannot be combined with
-fsanitize=thread and/or -fcheck-pointer-bounds.
