For what it's worth, I was able to build* with gcc/g++-4.9 in my x86 VM.
There were memory usage improvements made in 4.9 which might be helping
here.

* The build failed due to running out of disk space instead of running
  out of memory.

I couldn't figure out how to tell debian/rules to use gcc/g++-4.9, when
testing this, so I just added gcc/g++ scripts in $PATH that exec'ed
gcc/g++-4.9.
