Any idea if this is because your clang is too old, or because it only
knows of __attribute__((alloc_size(x,y)) which is what is documented at
https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html#index-g_t_0040code_007balloc_005fsize_007d-function-attribute-3080
?

According to
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20120521/058005.html
clang has support for this attribute.
