Unfortunately, the actual error did not show up in the excerpt, due to a
multithreaded build, but it is the following clang error:

  *** Bad machine code: Using an undefined physical register ***
  - function:    _ZNK7WebCore8Position10downstreamENS_27EditingBoundaryCrossingRuleE
  - basic block: BB#54 lpad12 (0x2c731100)
  - instruction: %vreg169<def> = COPY %EAX; GR32:%vreg169
  - operand 1:   %EAX
  fatal error: error in backend: Found 1 machine code errors.
  clang++: error: clang frontend command failed with exit code 70 (use -v to see invocation)

This has been reported as <http://llvm.org/bugs/show_bug.cgi?id=16038>,
but it is not fixed yet.  Currently, the only workaround is to compile
with -march=pentium3 or higher.
