Should I presume this to be a GCC bug? It could be, but you need to localize the problem to make sure. You could try compiling some files with GCC 3.3.2 and some with GCC 3.4.4, and determine which file makes the difference. Then you could try splitting that file in various ways, to compile part of it with 3.3.2 and part with 3.4.4. That way you can see which function fails. At that point, you'll probably see that either the function contains code that is not well defined in C, or that it has been miscompiled by GCC 3.4.4. Either way, we will know what to do.
