Synopsis: Optimization (>= -O2) with bitfields yields incorrect result

State-Changed-From-To: open->closed
State-Changed-By: jakub
State-Changed-When: Sun Apr 21 14:35:13 2002
State-Changed-Why:
    Your testcase is ill-formed, uses illegal type-punning.
    Please see info gcc on -fstrict-aliasing (which is
    the default in these gcc releases at -O2 and above).
    Either compile with -O2 -fno-strict-aliasing or fix
    the code in question (e.g. to access the objects through
    unions).
