Narrative:
Air carrier medium large transport a had been cleared taxi runway 36, hold short of runway 3 on taxiway charlie. We stopped just short of charlie with an air carrier large transport B on charlie. An air carrier large transport C was pushed off the south finger. The tower cleared the air carrier large transport B air carrier to cross runway 3. As the brakes were released the first officer looked to the right for clearance and observed a twin turbo propeller cpr light transport D 'south' turning between our aircraft and air carrier large transport C. Brakes were reapplied to prevent a collision. Ground control wanted us to close up the interval with air carrier large transport B and we responded that we stopped to avoid a conflict with the twin cpr light transport D. Suspect that aircraft was on different frequency. Twin proceeded to corporate ramp. No response was heard on G frequency. Very dangerous situation.
