Either way, it would be quite useful to debug it. A first step is to compile some files with -O and some with -O3. By trying that in different ways, you can find out which file the problem is in. I would suggest binary search: first try compiling half the files with -O3, then you'll know it's in one set of half the files. Then divide thst set in half, etc.
