an aorist (2/3sg počrъpe is attested in the 12th c. (počrětъ first in the 15th), so the prs stem may have been generalized to distinguish it from supine počrětъ (attested in Mar./Zogr. Jn 4:7, Assem.: počrъpatъ)
otherwise, aor/inf stem črě- reflects aor *(s)kérp-s- (LIV 559) well
inf črěsti also attested (in 14th c.), as well as počrъsti (in the Legend of Troy 895)
