kcc,
Any chance that we can get http://llvm-reviews.chandlerc.com/D216 approved
and committed
into llvm so that the libsanitizer merge can also eliminate the need for the
Core Foundation

Unfortunately
diff #518 has bit-rotted against current compiler-rt svn so Alexander will need
to correct
the patch for that.
