Synopsis: invalid expression evaluation in gcc

State-Changed-From-To: open->analyzed
State-Changed-By: jakub
State-Changed-When: Thu Feb 21 08:37:24 2002
State-Changed-Why:
    There is no sequence point in C after first operand of
    < operator, so your testcase has undefined behaviour.
    See ISO C99 Annex C, for example.
    There are sequence points after first operand of comma
    and at the end of if controlling expression, but there is
    nothing which requires < operands to be evaluated in any
    specific order.
