hg: jdk7/hotspot-comp/hotspot: 6973963: SEGV in ciBlock::start_bci() with EA

[John Cuthbertson]

Hi All,

Yes it's already fixed. I discovered it after building on intelsdv03 
which has gcc 4.1.2 installed. The jprt machines have gcc 4.3 which 
doesn't flag the assignments. As Ramki said it should be propagated to 
hotspot/hotspot sometime today.
