Nop, there was indeed nothing in the trace at all (even not an uninitialized jump in any third party library). You may want to try callgrind instead of valgrind to have a backtrace on where E is spending his time if you can't reproduce the memory corruption, maybe that would point to something. >> You should be able to get the problem under Xephyr >> to (at least try there first, if it doesn't show anything, then you >> are good for a slow motion session). > Do you mean that I could use valgrind under Xephyr to track the memory > usage of an already running E when it segs, just as I would attaching > gdb to it? > Currently when I need to use valgrind I invoke it via xinit. Well, it is required to run from the beginning. So you will have a 'Xephyr :1.0' running and then 'enlightenment_start -valgrind -display :1.0'. It should give you something on the console. The main things is that Xephyr doesn't allow OpenGL, so you will have E switching back to software. This may change the profile usage of E, so it is useful only to try catching the memory corruption. -- Cedric BAIL ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
