It depends. If the system is sufficiently resource constrained that 
malloc() is actually telling you that you're not going to the moon, more 
RAM will help. But what's more likely is that it's running out of 
process address space - a 32 bit process can only address 3GB of address 
space (which isn't necessarily all RAM), no matter how much RAM is 
available[1]. Adding more RAM isn't going to help there. Getting rid of 
32-bit build systems is.

[1] On x86, anyway. I don't know what the ARM VM split is.
