Reproduce: - Open the attached test program compilation_test.c in Emacs - M-x compile - Enter compile command "gcc -c compilation_test.c"In the resulting *compilation* buffer, there should be a mixture of "error", "warning" and "note" messages. Trouble is they're all parsed as errors - hence they're all coloured in red, and querying any one's type by moving point onto it and evaluating "(compilation--message->type (get-text-property (point) 'compilation-message))" always returns 2, though warnings should return 1 and notes should return 0. Commands that jump between previous/next error also behave correspondingly wrongly.
Fix:The attached fix_compilation_message_type.patch, applied to Git master, fixes it for me.
It seems like the old code was accidentally using the same variable for the TYPE field of the current rule from compilation-error-regexp-alist, and in an inner loop, the actual type that the current message from the compilation buffer was resolved to be, so the resolved type of the first message tends to get carried down into the following ones.
