XCB crash while Video Rendering in multithreded application

I encounter the following crash on RHEL 7.0 when I run a multithreaded video rendering application using GLFW and OpenGL. OpenGL version is 2.1 and MESA version is 9.3.0

Following is the back trace of the multi-threaded program I am working on:

fracplanet

FRACPLANET(1)							    Fracplanet							     FRACPLANET(1)

NAME

       fracplanet - Create and view random fractal terrain and planets.

SYNOPSIS

       fracplanet [ <QtOptions> ] [ --help ] [ --verbose ] [ --display-list ] [ --invert-mouse-y ] [ --wireframe ]

DESCRIPTION

       Fracplanet generates random planets and terrain with oceans, mountains, icecaps and rivers.  Parameters are specified interactively and the
       results displayed using OpenGL.	The generated objects can be exported for Pov-Ray or Blender.

       A document fully describing usage via the application's GUI is accessible from the application's "About" menu once it is running.

GENERAL OPTIONS

       <QtOptions> Standard options recognised by the Qt toolkit (for example -geometry <width>x<height>  Note	that  these  use  the  single-dash
       option style.  ).

       --help, -h Display a list of recognised arguments.

       --verbose, -v Display information about fracplanet and the GL graphics system it's running on.

RENDERING OPTIONS

       These affect the initial settings on the render controls tab, which controls the OpenGL display.

       --display-list, -d Start up the application with rendering in display list mode by default (c.f immediate mode).  This is particularly use-
       ful when the application is running remotely as the generated meshes are then only sent to the local OpenGL display hardware once.

       --invert-mouse-y, -y Start application with mouse in non-joystick mode for flight.

       --wireframe, -w Start application with rendering set to wireframe mode.
