In the last sentence under remarks, the article says:

"..; for x64 compilers it is 4K and 8K respectively."

Respecively to what? 4k is 4096 - so why the difference?

Does the remark mean that fo X86 compilers, the routine is called when local variables exceed 4k (4096 bytes) while for X64 compilers when they exceed 8k (8192 bytes)? Or something else?
