Ah, I was actually just about to compile a list with the changes that went into gcc-4.9 after -10 which was still working, so thanks for that. I haven't worked with the gcc code base before, so any suggestions on how to work through the code? I would just checkout the code from git://gcc.gnu.org/git/gcc.git now and revert change after change to see if that fixes it. Adrian
