Problem description =================== I've noticed this problem several times when editting C / C++ files. I'm in C++ major mode, with or without font-lock. The line I'm trying to edit is... gen_concept::gen_concept() I get as far as the 2nd colon, at which point the system crashes and coredumps. I have seen this with % characters from my SWIG header files. Interestingly, although I can reliably reproduce this crash, I have used this exact installation to edit 1000's of lines of C++ with very little trouble. I can make the system crash without doing any editting by issuing the command M-x c-electric-colon Xemacs version ============== xemacs --version XEmacs 21.5 (beta9) "brussels sprouts" [Lucid] (sparc-sun-solaris2.7) Installation details ==================== uname -a: SunOS trex 5.7 Generic_106541-20 sun4u sparc SUNW,Ultra-5_10 ./configure '--prefix=/hm/npavey/bin/xemacs-21.5.9' XEmacs 21.5-b9 "brussels sprouts" configured for `sparc-sun-solaris2.7'.
