  Multiple alpha coincidence and correlations are studied in the reaction
$^{12}$C+$^{12}$C at 95 MeV for fusion-evaporation events completely detected
in charge. Two specific channels with Carbon and Oxygen residues in coincidence
with $\alpha$-particles are addressed, which are associated with anomalously
high branching ratios with respect the predictions by Hauser-Feshbach
calculations. Triple alpha emission appears kinematically compatible with a
sequential emission from a highly excited Mg. The phase space distribution of
$\alpha$-$\alpha$ coincidences suggests a correlated emission from a Mg
compound, leaving an Oxygen residue excited above the threshold for neutron
decay. These observations indicate a preferential $\alpha$ emission of
$^{24}$Mg at excitation energies well above the threshold for $6-\alpha$ decay.
