Cygwin Fucking Up with C++

I'm trying to get some experience with using a command prompt to compile C++ programs. I got Cygwin installed with everything, so I try to compile a .cpp with g++. For purposes of this thread, i'll use a Hello World program.

I do
$ g++ main.cpp -o HelloWorld

And I get this shit:
      3 [main] ? 1452 init_cheap: Couldn't reserve 3600336 bytes of space for cygwin's heap, Win32 error 487

What the fuck, /prog/? I tried doing this stuff on another computer (at work) and everything ran just fine. But if I try to do this on my home laptop here, it fucks up. What's going on, and how do I fix it?

A quick google of that error says to re-install cygwin and try again. If that doesn't work, try googling around yourself.
