------- Comment #5 from manu at gcc dot gnu dot org 2009-02-12 11:22 -------
At the moment of warning, the compiler does not know that the uninitialized
variables are only used if they have been set before. Hence, the warning.
This will require conditional PHIs (or some other way to detect that some PHI
operands are never reached).
