malloc(0x88) failing again

[Bruce Korb]

I rebooted and ran the libposix tests again:

FAIL: test-dprintf-posix2.sh
FAIL: test-fprintf-posix3.sh

So, we're back to where the system itself is in a funny
state where these two programs fail and it is in the
/lib64/libc.so code.  I have a fix for this.

I'm sure that you'll like it:
