Mam>x m>imum Java heap size of a 32-bit JVM on a 64-bit OS
The question is not about the mam>x m>imum heap size on a 32-bit OS, given that 32-bit OSes have a mam>x m>imum addressable memory size of 4GB, and that the JVM's mam>x m> heap size depends on how much contiguous free memory can be reserved.

In PHP what does it mean by a function being binary-safe?
