Re: [ros-dev] [ros-diffs] [greatlrd] 22195: make malloc, calloc and some other function return NULL if size is 0

[Magnus Olsen]

I talk with filip about it, he confrim the fix is correct

IEEE spec did mentor it exists two diffent behvoir
on malloc(0). My windows 2000 is return NULL from
malloc(0) and some other windows I got did not.
