9415.0. "osf_qar #52386; any idea is appreciated..." by HYDRA::SHEN () Mon Apr 07 1997 17:00

    A customer's X11 appliin X11 library's memory management. A 3rd degree report is generated
    and
    attached here showing that the application was trying to free memory
    beyond what was allocated by X11. The customer was gentlely suggested
    that this probably was an application error, however they are not
    convinced. How do you think ? What other information can we ask the
    customer to provide to determine that this is really not an X11
    problem ? Any ideas are appreciated.

    Looks like it's a bug in the X11 library (that's hardly a news :-().
    Any help will be appreciated.
