Hello, c++-mode seems to misinterpret statements like | if (c<0 || c>99) as some kind of template specification. With enabled syntax-highlighting and completion mode, this will lead to severe confusion of the highlighting system. E.g. when a file 'foo.cc' contains int main() { if (c<0 || c>99) {} } I can reproduce it with: | $ xemacs -vanilla | M-x load-library<CR>completion | select 'Options -> Syntax Highlighting -> In This Buffer' in the menu | C-x C-f foo.cc | press 'C-f' subsequently until the '0' will be reached (from 'c<0') Now, I get: | (1) (error/warning) Error in `pre-command-hook' (setting hook to nil): (error Containing expression ends prematurely) The stack-trace is | Signaling: (error "Containing expression ends prematurely") | scan-sexps(22 -1) | symbol-under-point() | symbol-under-or-before-point() | use-completion-under-or-before-point() | completion-before-command() It is impossible to insert certain characters (e.g. '=' or ';') here; with my other settings (sorry, I do not know a minimal setup), the entire paren-highlighting breaks (expressions keep marked forever). I am using latest package set (cc-mode 1.40). Enrico
