Test program to show the issue
I'm getting null argument warnings when there is an explicit test for non-null
right before the statement that provokes the message. The attached test
program shows this; when compiled with -Wall -O1 or -Wall -O2 you see two
warnings. Both should be suppressed; the "for" end condition is the non-null
test, and then in the second case there is an additional test right on the
statement that is rejected as well.
