[Octave-bug-tracker] [bug #54920] AutoScale in xscale = log mode may lead to an unexpected error

[Rik]

Follow-up Comment #25, bug #54920 (project octave):

I compiled with ASAN to look for memory leaks and I'm finding this 8-byte leak
repeated multiple times.


Direct leak of 8 byte(s) in 1 object(s) allocated from:
    #0 0x7f7b612ea458 in operator new(unsigned long)
(/usr/lib/x86_64-linux-gnu/libasan.so.4+0xe0458)
    #1 0x7f7b5f233601 in
octave::type_info::register_type(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&,
std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char>
> const&, octave_value const&, bool)

    #2 0x7f7b5f31f312 in

    #9 0x7f7b591ac121 in QObject::event(QEvent*)

    #10 0x7f7b59efa82b in QApplicationPrivate::notify_helper(QObject*,
QEvent*) (/usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5+0x15482b)


I haven't verified yet by going back before changeset 26277:e92a44730a6e, but
it looks related to this report.
