I had to compile a C++ program today on a VPS with 2 gigs of ram. the base ubuntu 12.04 install took 115MB of ram. For some reason when linking the libs at the end the program shot above 2 gigs of ram and got killed by the openvz system. took me a while of googling but the answer to my woes was multi fold,

1. I switched from a debug build to a release build which was much more optimized.
2. I added the following to my Cflags :
   1. CFLAGS=”–param ggc-min-expand=0 –param ggc-min-heapsize=8192″

Dont both of those things cleared up my issue in no time.
