Description Ian Collier 2013-05-03 13:42:10 EDT
Created attachment 743309 [details] Test case Since updating ncurses to 5.9-10.20130413, some terminal-based editors no longer work correctly. This applies to both F17 and F18. Version 5.9-7.20121017 definitely worked. A testcase is attached. It should insert the word "hello" before the word "world", pausing for a key-press after each letter. However, it just succeeds in moving the cursor without displaying the inserted letters. It was tried in both an xterm and a gnome-terminal, each with TERM=xterm. Removing the COLOR_PAIR attribute from the character to be inserted makes the program work. (The colours themselves are largely irrelevant; it seems to be the presence of the attribute in the argument to insch() that triggers the bug.)

thanks - I can see some breakage (will investigate).
Comment 3 Thomas E. Dickey 2013-05-11 14:33:58 EDT
The cause was the fix noted here: http://invisible-island.net/ncurses/NEWS-contents.html#t20121215 Essentially, Coverity pointed out that the comparison I was making was always true due to a macro. I removed the macro without noticing the reason I'd used it originally. I'm reworking that part of the code, and the fix will be in today's patch.
