Hi everyone, I have a situation when my application crashes after several days of running. I've discovered that the bug is in libX11 library. I have a 32bit openSuse 12.2 system. https://bugs.freedesktop.org/show_bug.cgi?id=71338 http://lists.x.org/archives/xorg-devel/2013-November/039007.html After I've applied the patch from http://patchwork.freedesktop.org/patch/16297/ the application worked.
The function src/xcb_io.c: void _XSend(Display *dpy, const char *data, long size) has some inconsistency which leads to crash, because of mixing of different variable types. I've discovered that the variable declarations are not as it must be, because depending of the installed system 32/64 bit the "unsigned long" type will be 32 or 64 bit. So "unsigned long" is not a good declaration for using a 64bit type (use uint64_t instead). Some places with variable declarations: ----- src/xcb_io.c: uint64_t requests (local in void _XSend(Display *dpy, const char *data, long size)) src/xcb_io.c: uint64_t sequence; (local in void _XSend(Display *dpy, const char *data, long size)) src/Xxcbint.h: uint64_t last_flushed; include/X11/Xlib.h: unsigned long request; src/Xxcbint.h : unsigned long sequence; ----- As a conclusion, you can harmonize variables type declarations that are overall the same.
