[Bug c/27224] New: Read twice and write on a variable in same expression

[moura at kdewebdev dot org]

The compiler doesn't warn when you read a variable twice in an expression where
you also write it.

Look at http://www.research.att.com/~bs/bs_faq2.html#evaluation-order to see
the description of the problem.

(GCC) 3.4.4 (mingw special)
c++ -Wall -pedantic -ansi
