Are all the compiler binaries 64-bit executables? gcc should not run out of memory until malloc or mmap fail to allocate any more memory. There is no maximum heap size. gcc's garbage collector doesn't run at arbitrary times; in particular it doesn't run when there is an allocation failure, nor when the heap reaches a certain size. Ian
