  <p>This does NOT occur with arm-none-eabi-gcc 4.7.</p>
  
  <p>This is one of the OS build files, so I don't want to mess with it -- and I've never seen gcc itself encounter a segmentation fault while building. Additionally, it occurs when building any of project, even ones entirely unchanged from the root ChibiOS repository.</p>
  
  <p>Any advice on diagnosing this problem?</p>
