We discuss the properties of the gas of primordial stringy black holes possibly formed in the high-curvature phase preceding the bouncing transition to the phase of standard cosmological evolution. We show that the regime dominated by such a string-hole gas can be consistently described by explicit solutions of the string effective action including first-order alpha' corrections. We present a phase space analysis of the stability of such solutions comparing the results obtained from different actions and including the possibility of O(d, d)-symmetric configurations.
