[Github-comments] [geany/geany-plugins] Splitting a snowman in half crashes Geany with Spell Check (inserting a space before Unicode VARIATION SELECTOR-16) (#1041)

Well, at least that one basically doesn't make any sense in C with the types involved.  It's not mimicking the syntax for 99.8% identical behavior and .2% surprise :grin: 

> @b4n now that you are returning `nullptr` from `pixels()` but you did not put a check for that on the return value of every use of pixels() all you have done is shift the problem. :stuck_out_tongue_winking_eye:

Not really: at least to the C guy I am, reading 0 bytes from `nullptr` or 0 bytes from a valid pointer doesn't seem much different.

Agreed.  I wanted to understand the issue and then provide a patch that Fedora could use to stop these repeated crashes.  Now it'll be time to hand it out to Neil and let it live :)

> @b4n @codebrainz just think of C++ as Sea++ a language which no longer has a connection to C, and that does its own thing, like Java or D, thats effectively what it has become smile

And they kept the C syntax weirdies like `&array[index]`, very clever on their part :stuck_out_tongue_closed_eyes: 

OK, enough trolling about C++ on my part for the moment :slightly_smiling_face:
