A change to GCC for a recent release coupled with a kernel bug has created a messy situation, with possible security implications. GCC changed some assumptions about x86 processor flags, in accordance with the ABI standard, that can lead to memory corruption for programs built with GCC 4.3.0. No one has come up with a way to exploit the flaw, at least yet, but it clearly is a problem that needs to be addressed.
