Narrative:
Aircraft X, on taxi out, contacted ground and was cleared, 'hold short runway 27 at taxiway B.' airbus on taxiway V came on frequency and queried his taxi instructions. Airbus was given, 'cross runway 27 at taxiway B.' aircraft clearance was changed, 'hold short of runway 27 at taxiway Y.' first officer of aircraft X notified ground of a B727 pushed back onto taxiway V, blocking taxiway Y. Aircraft X requested taxiway B and ground amended clearance, 'cleared to cross runway 27 at taxiway B.' after crossing taxiway B hold line, short of runway 27, an airbus pushed tail west onto taxiway V from spot. Push-out resulted in close wingtip spacing with aircraft X. Aircraft X stopped taxi and notified ground that aircraft was holding short of runway 27, beyond hold line, due to wingtip spacing conflict with airbus pushing onto taxiway V. Next acknowledgement from ground was for aircraft X to turn off taxi lights, shortly followed by a DC10 passing on takeoff on runway 27. Ground asked to confirm, we reported 'beyond taxiway B hold line.' after aircraft passed, ground gave aircraft X clearance to continue to runway 18L via taxiway B, taxiway Y.

Title: A DC10 CREW AT MEM MOVED ACROSS THE HOLD LINES TO MAINTAIN WINGTIP CLRNC FROM A B727 PUSHING BACK, RESULTING IN A RWY INCURSION WITH ANOTHER DC10 TAKING OFF ON RWY 27.
Narrative: ACFT X, ON TAXI OUT, CONTACTED GND AND WAS CLRED, 'HOLD SHORT RWY 27 AT TXWY B.' AIRBUS ON TXWY V CAME ON FREQ AND QUERIED HIS TAXI INSTRUCTIONS. AIRBUS WAS GIVEN, 'CROSS RWY 27 AT TXWY B.' ACFT CLRNC WAS CHANGED, 'HOLD SHORT OF RWY 27 AT TXWY Y.' FO OF ACFT X NOTIFIED GND OF A B727 PUSHED BACK ONTO TXWY V, BLOCKING TXWY Y. ACFT X REQUESTED TXWY B AND GND AMENDED CLRNC, 'CLRED TO CROSS RWY 27 AT TXWY B.' AFTER XING TXWY B HOLD LINE, SHORT OF RWY 27, AN AIRBUS PUSHED TAIL W ONTO TXWY V FROM SPOT. PUSH-OUT RESULTED IN CLOSE WINGTIP SPACING WITH ACFT X. ACFT X STOPPED TAXI AND NOTIFIED GND THAT ACFT WAS HOLDING SHORT OF RWY 27, BEYOND HOLD LINE, DUE TO WINGTIP SPACING CONFLICT WITH AIRBUS PUSHING ONTO TXWY V. NEXT ACKNOWLEDGEMENT FROM GND WAS FOR ACFT X TO TURN OFF TAXI LIGHTS, SHORTLY FOLLOWED BY A DC10 PASSING ON TKOF ON RWY 27. GND ASKED TO CONFIRM, WE RPTED 'BEYOND TXWY B HOLD LINE.' AFTER ACFT PASSED, GND GAVE ACFT X CLRNC TO CONTINUE TO RWY 18L VIA TXWY B, TXWY Y.
