VS 2008 uses dynamically allocated memory for the application and a fixed sized 
heap for precompiled headers (pch). The /Zm options affects the PCH fixed-size heap.

Generally speaking, if the PCH is too big you would need to increase the value 
of /Zm or decrease the number of header files within the PCH.

IIUC there are no precompiled headers involved in your case, so what could 
happen is that /Zm1000 is too big a value (allocates 750 mb). That is: /Zm 
reserves too much memory to the PCH, leaving less memory for the aplication. The 
out of heap space could be a consequence of that, so try removing /Zm or 
decreasing its value.
