This bug report will be sent to the XEmacs Development Team, not to your local site managers!! Please write in English, because the XEmacs maintainers do not have translators to read other languages for them. In XEmacs 21.2 (beta32) "Kastor & Polydeukes" [Lucid] (i686-pc-linux, Mule) of Sat Apr 8 2000 on lotusland.demon.co.uk configured using `configure --with-gcc --ldflags=-Wl,-E --dynamic --debug=yes --error-checking=all --with-dialogs=athena --with-scrollbars=lucid --with-widgets=athena --with-sound=native --with-mule' Please describe exactly what actions triggered the bug and the precise symptoms of the bug: `M-x gdb' on a program. Set a breakpoint, and then give gdb an `r' to run the program. Xemacs crashes when attemptimg to display the source line of the breakpoint in the source window. The failing assert() is at redisplay-x.c:482.
