FYI, I looked closely to the code.

The Mesa error came from ogl-samples file "framework/glew.c", line 9535
(extStart = glGetString(GL_EXTENSIONS);).

This GLEW file is the official glew.c version 1.10.0.

And I finally understood that there is two problems:

- current GLEW version doesn't check the GL version and always calls
glGetString(). A patch was submitted more than 2 years but still need to be
commited:
http://sourceforge.net/p/glew/bugs/174/

- GLEW currently doesn't supports core profile:
http://sourceforge.net/p/glew/bugs/209/
and
https://www.opengl.org/discussion_boards/showthread.php/169661-Forcing-Core-Profile-in-GLEW

So I guess ogl-samples should not use GLEW.
