Valgrind notes

Leak check

valgrind \
    --undef-value-errors=no \
    --log-file=leaks.log \
    --num-callers=30 \
    --leak-check=full \
    --track-origins=no \
    "$@"

• Reachable blocks (those to which a pointer was found) are not shown.
  To see them, rerun with: --leak-check=full --show-reachable=yes
• Use --undef-value-errors=no to disable conditional jump and other undef value usage display.

Memory corruption check

valgrind \
    --leak-check=no \
    --track-origins=yes \
    --log-file=corruptions.log \
    --num-callers=30 \
    "$@"

• Use --track-origins=yes to see where uninitialised values come from. --track-origins is slow. First time run slow tests without it.

• Use --demangle=no to get mangled names (suppressions doesn't work with demangled names).
