Flying the DRLLR ONE arrival into IAH we complied with the descend via instructions with no issues. At the fix DOMNO the arrival and the flight plan in the FMS had VLDEZ after DOMNO on a 087 heading. With the autopilot on the FMS never started the turn to VLDEZ and continued on our heading through DOMNO; and kicked into ROL mode. The Captain was pilot flying and quickly took control and started a turn back on course.  ATC never inquired therefore we never brought it up. The rest of the arrival was normal. With both the pilot flying and pilot monitoring the undesired aircraft state was limited and quickly corrected. We were aware of going into ROLL mode at the end of the STAR but did not expect it at DOMNO. Realized the FMS did not make the turn to VLDEZ and take action before completely passing through DOMNO.
EMB145 First Officer reports his aircraft failing to turn for VLDEZ over DOMNO on the DRLLR 1 RNAV to IAH. Manual intervention is required to turn the aircraft toward VLDEZ.
