Synopsis: gcc-3.1.1 (debian/i386): wrong code with -O2 / bitfields / pointer aliasing

State-Changed-From-To: open->closed
State-Changed-By: sirl
State-Changed-When: Fri Aug  9 12:05:00 2002
State-Changed-Why:
    You have written undefined C code (hint: the compiler is
    free to assume that fs, *f and *p are diffrent objects),
    either fixup your code or compile with -fno-strict-aliasing.
