* RBOB gasoline dive triggers brief NYMEX trading halt
* U.S. crude, gasoline stocks jumped last week - EIA

NEW YORK, May 11 U.S. crude oil futures fell more than 5 percent on Wednesday after an unexpected jump in gasoline inventories reported by the government sent RBOB gasoline futures into a tailspin.
RBOB gasoline futures' 25-cent slump intraday triggered a five-minute trading halt on the New York Mercantile Exchange for the motor fuel, heating oil and crude oil futures, the first such trading stoppage since the 2008 financial crisis.

Distillate stockpiles fell 843,000 barrels, the EIA said.
Before the release of the data, a Reuters survey of analysts had forecast crude stocks to be up 1.4 million barrels, with gasoline inventories seen down 200,000 and distillate stockpiles up 400,000 barrels.
Crude futures were pressured ahead of the inventory data by concerns about slowing economic growth in China and the dollar's strength amid continuing euro zone debt worries.
