[Octave-bug-tracker] [bug #57591] Segmentation faults when running the test suite (mostly with clang)

[Pantxo Diribarne]

Follow-up Comment #43, bug #57591 (project octave):

@John: The GUI Object (a Figure here) already stores a reference to the
underlying graphics_object, see this excerpt from Object.h:


    // Store the graphics object directly so that it will exist when
    // we need it.  Previously, it was possible for the graphics
    // toolkit to get a handle to a figure, then have the interpreter
    // thread delete the corresponding object before the graphics
    // toolkit (GUI) thread had a chance to display it.  It should be OK
    // to store this object and use it in both threads (graphics_object
    // uses a std::shared_ptr) provided that we protect access with
    // mutex locks.
    graphics_object m_go;


After this addition, we should have changed all the logic and removed m_handle
since m_go lets us access the object directly.

Anyway, is it me or what we see in the backtrace is a crash in Mesa, not in
Octave?
