What gcc flags are you using to enable graphite? Usually, -floop-interchange, -floop-strip-mine, and -floop-block are enough. One can go further with -ftree-loop-distribution and -ftree-vectorize and maybe even others. AFAIK these extra graphite options may cause problems. Regarding LTO, I experienced a severe problem with ghostscipt due to what I later traced to LTO: http://bugs.ghostscript.com/show_bug.cgi?id=691768 Ever since that time I disabled LTO completely.
