[Github-comments] [geany/geany] Fix clang warnings: Use empty array instead of NULL pointer (#2889)

[elextr]

@rootkea If you are using the same options as [here](https://github.com/geany/geany/issues/2891#issuecomment-913481562), especially -O0 that might explain why the compiler does not notice the protection of the null check.  IIUC compilers need something like -O2 to do the data flow analysis that such checks depend on.  Maybe you could check if you get the warnings with -O2?
