Sad to say, folks, that I've been seeing this bug VERY intermittently on multiple generations of hardware, although I think I can safely make these assertions: -only since GTK became widespread (this definitely did not occur back in the Athena, Motif, OpenWindows, etc. days) **specifically, I don't think I've ever seen this bug appear when I wasn't running GTK+-linked or GTK2-linked software** -only since GL extensions became widespread (including software, e.g. MESA) -mostly but not exclusively on Linux systems (at least once under Solaris shortly after GNOME became the default desktop) -some (hardware) systems tended to produce this error more than others -certain applications tend to cause it more often than others (notably Synaptic, per the Ubuntu reports) -I *think* higher compiler optimization causes it to happen more often, not sure -not exclusively on multiprocessor systems: I've definitely seen this error on a Pentium III 1.0GHz (ULV mobile) and a Sparc IIi (~400MHz?).
It's almost certainly a race condition, since nothing else would produce this sort of intermittent behaviour across 10+ years and multiple hardware platforms. It may not be a regression - it's likely we're dealing with a design flaw that has existed since <some piece of code> was written, but is being triggered more and more often because of the proliferation of multiprocessor platforms with multithreaded libs and multithread-generating-compilers. Unfortunately, this all means that finding it will be nearly impossible. So much for the "all bugs are shallow" theory :-). Or it could just be something low-level in GTK, which would explain why it's been cropping up more and more. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/507062 Title: synaptic assert failure: synaptic: ../../src/xcb_io.c:385: _XAllocID: Assertion `ret != inval_id' failed.
