     Java HotSpot(TM) 64-Bit Server VM (25.0-b60-BASE_rdurbin-fastdebug) for windows-amd64 JRE (1.8.0), built on Nov 20 2013 22:06:54 by "rdurbin" with MS VC++ 10.0 (VS2010)

     Build windows_amd64_compiler2/fastdebug time: 2.93 minutes.

See the attached hs_err_pid file.

The scenario:

- clone Main_Baseline to base_repo
- clone base_repo exp_repo
- execute parallel fastdebug builds in both repos
- one of the builds should fail with the above
