In my experience, gdb easily gets confused when function pointers are involved. I've had one or two coredumps while working on the x11 DRI driver where it wouldn't even print a backtrace. In every case that's been because an unintialized function pointer was being called/dereferenced. gdb 6.0 appears to handle this case much better than 5.x did. - ajax ------------------------------------------------------- This SF.Net email is sponsored by Sleepycat Software Learn developer strategies Cisco, Motorola, Ericsson & Lucent use to deliver higher performing products faster, at low TCO. http://www.sleepycat.com/telcomwpreg.php?From=osdnemail3 -- _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
