If a list is preceded by an align-pad, then accessor for the end-iterator returned a wrong value. Reason: the length of the align-iterator was added to a pointer of list-member type. Therefore, the length was multiplied by the size of the list-member type, due to C pointer arithmetic rules. This has looked like the following, e.g., in xcb_randr_get_crtc_transform_pending_params_end: i.data = ((xcb_render_fixed_t *) prev.data) + ((-prev.index) & (4 - 1)) + (R->pending_nparams); This bug was introduced with the following commit: http://cgit.freedesktop.org/xcb/libxcb/commit/?id=4033d39d4da21842bb1396a419dfc299591c3b1f The fix handles this by casting to char* before adding the align, and then casting the result to the member type.

About libxcb ============ libxcb provides an interface to the X Window System protocol, which replaces the current Xlib interface. It has several advantages over Xlib, including: - size: small, simple library, and lower memory footprint - latency hiding: batch several requests and wait for the replies later - direct protocol access: interface and protocol correspond exactly - proven thread support: transparently access XCB from multiple threads - easy extension implementation: interfaces auto-generated from XML-XCB Xlib can also use XCB as a transport layer, allowing software to make requests and receive responses with both, which eases porting to XCB. However, client programs, libraries, and toolkits will gain the most benefit from a native XCB port. Please report any issues you find to the freedesktop.org bug tracker, at: <https://bugs.freedesktop.org/enter_bug.cgi?product=XCB> Discussion about XCB occurs on the XCB mailing list: <mailto:xcb at lists.freedesktop.org> <http://lists.freedesktop.org/mailman/listinfo/xcb> You can obtain the latest development versions of XCB using GIT. For anonymous checkouts, use: git clone git://anongit.freedesktop.org/git/xcb/libxcb For developers, use: git clone git+ssh://git.freedesktop.org/git/xcb/libxcb
