with '-O1 -ftree-vrp -fwrapv' the armencrypt.test from
gnupg-1.4.5 release producing an output until ENOSPC.

with '-O1 -fno-tree-vrp' test passes.

$ cd gnupg-1.4.5/checks/
$ srcdir=. ./armencrypt.test
$ ls -l x
-rw-------  1 builder2 users 108946 Oct 23 10:32 x

this bug is specific for big-endian.

gcc-4.1.2-20060928.
