Re: [Bug: 21.4.17] Assertion failure in redisplay-output.c

Ed> Fatal error: assertion failed, file redisplay-output.c, line Ed> 1595, db->xpos >= 0 && db->ypos >= 0 Thanks for your post! This error has been reported before. It's deep in the C code, and without a C backtrace it's impossible to diagnose (except by reviewing all of the several thousand lines of code that make up redisplay). If you happen to have a core file that you can get a backtrace from, we would really like to see that backtrace.
