So... Will the issue be resolved?

SOLVED by using clang instead of gcc and clang++ instead of g++!

After playing with git bisect I downgraded the Blender source down to commit from April 27 and my problem persisted. Blender still crashes when I use -O2 or -O3 optimization flags. So looks like the problem is really environment specific. If anyone of Blender devs uses Arch Linux and has working Blender built with GCC 4.9 and -O3, please share CMake cache file or Scons config and Pacman log file, so I could compare. Campbell Barton?

4.7 is not an option, because Arch Linux is a so called "rolling release" guy. Installing GCC 4.7 means doing it from source into separate directory being at risk to mess the versions, which I just don't want to mess with. Not to mention building the monster from source is a daunting timespending.
GCC 4.7 is not an option for me. As I said, before May 12 -O3 worked fine with GCC 4.9, now even -O2 makes crashy executable. For the time I'll settle on what works: -O1. I hope you will investigate and resolve this nasty issue.
So, here are some results of my investigation.
Blender works again for me, when I compile it with compiler optimization flag -O1 or even without it. If I build with -O2 or -O3, Blender crashes.

Will core dump with my binary help? If they will how should I hand them over to you?

Probably my cmake cache file would help
OK. Downloaded last build from buildbot (2014-05-12 hash 47e9057) and it's working. Looks like the problem is current Arch Linux specific.
I build myself using CMake
Maybe trace helps
The bug is much more disasterous! It also affects some other interface parts. For example:
- Open Blender and stay in default scene.
- Add a plane.
- In the left tool panel check "Align to view" checkbox.
- Segmentation fault.

- I didn't try this on Windows, so can't say anything about this.
- I found that the problem is not image specific. Blender crashes anytime I try to press Thumbnail view while opening file of ANY type (for example press F1 and try to turn on Thum view). Maybe the case is my Linux environment specific. For example I read recently, that transition to Python 3.4 in Blender is just started, but in ArchLinux upgrade to Py 3.4 has already been for a while.
