Dear developers, I've reproduce this several times on my ubuntu machine, but don't know what is wrong... I've also run xemacs in gdb, but it seemed that xemacs didn't hang. Only the GUI is not response anymore. I tried to press C-c in gdb and get a backtrace(don't know it is useful or not) #0 0x00007f93cbb596f3 in select () from /lib/libc.so.6 #1 0x00007f93cad991ae in ??
