[Bug c/23402] New: error: statement makes a memory store, but has no V_MAY_DEFS nor V_MUST_DEFS

[bunk at stusta dot de]

This is a compile error when trying to compile the file kernel/audit.c from the
Linux kernel 2.6.13-rc5-mm1 with a current CVS HEAD gcc.

I've removed many of the compiler flags that were present at the original
compilation. What triggers this problem is switching from -O0 (no problem) to
-O1 (see below).
