System Information
Ubuntu 14.04, Intel Graphics + Mesa DRI (3.0, 10.1.3)
Blender Version
Broken: 2.77

f337feaon Ubuntu 14.04, Blender 2.7722a2853on OSXShort description of error
Right-clicking on object/mesh causes Blender to crash.
Exact steps for others to reproduce the error
With fresh install of Blender 2.77 on Linux machine and Blender factory defaults, selecting an object/mesh by right-click causes Blender to crash. Right-clicking on selected item to make active also causes crash. Further, Box Selection of object/mesh causes a crash, but Circle Selection has no problem.
All work without issue: selection of camera, light, empty, etc.; selection of verts, edges, and faces in Edit Mode; selecting the object in the Outliner.

/me rings Intel driver issue bell ;) In most cases such issues can be solved as described here . Could you check this and report back if it solved your issue?
Changing User Prefs to use OpenGL Occlusion Queries does solve the selection problem in 2.77 for right-click selection and box selection. Thanks!
Since this seems like a typical Intel driver issue, is there a way to make "Automatic" use OpenGL Occlusion Queries with Intel cards? Or are there strong reasons to use to OpenGL Select with Automatic?

I should've bet on that :) This is not the first report about such issues in 2.77 (all Intel IIRC), not sure what could cause it.
CCing @brecht and @MikeErwin - maybe they have an idea on what could cause this and how to solve.

Hey @gfxcoder, check if upgrading your Mesa package resolves this. There was a bug in old Mesa which was exactly this (VBO + selection = crash) and fixed two years after we reported it :). I think it was sometime in 2014/2015 which is when your implementation came out, so there's a chance latest versions are fine.

Found the bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=59455
Looks like it is indeed older than 2014. Please update your Mesa library
Updating Mesa library to 11.1.2 did fix the problem. I can now use either OpenGL Select or Automatic without Blender crashing, although it is noticeably slower than OpenGL Occlusion Queries. Thank you for all your help!
