It isn't possible for us to tell what went wrong here.  There was no 
error printed in the output before make failed.

You didn't mention what gcc version you are trying to build.  If you are 
trying to building from mainline, then then keep in mind that these are 
development sources, and they are occasionally broken.

The first thing I would suggest is try continuing the build by running 
make bootstrap again.  If this is a real gcc bug, then it will be 
reproducible, i.e. it will fail at the same place everytime.  If it 
doesn't always fail at the same place, then the bug could be in some 
other part of the system.  Some PC hardware can be unreliable, e.g. 
overclocked systems, systems with memory that is starting to fail, etc., 
and this may show up while building gcc because gcc stresses the system 
by using lots of memory.

If this is a real gcc bug, then you should try to debug the problem. 
Run gcc (or rather cc1) under gdb to see where it is failing, and try to 
figure out why.  You might also look to see if a recent patch might 
explain the failure.  If a build worked last week, but not today, then a 
patch checked in since then must have broken it.
