--- Comment #13 from Dan Kegel dank@kegel.com 2008-01-12 02:42:40 --- Bingo: trace:x11drv:X11DRV_CreateBitmap (0x3e2c) 268599240x3403476 1 bpp
Those numbers are unreasonable. Now the trick is to find out where they came from. +relay,+x11drv,+synchronous might help here. Sometimes one has to add special TRACE statements just for the hunt.
(And I suppose some people use debuggers for this, but that's not my cup of tea.)
