<pre>Mesa Version: 10.2.7
CentOS: 7 updated as of today (24 June 2015).
Crashes when calling:
170 // Insert a fence to mark when this chunk is available for reuse.
171 chunk->m_fence = glFenceSync( GL_SYNC_GPU_COMMANDS_COMPLETE, 0 );
partial stack trace:
#14 0x00007ffff4736e49 in __run_exit_handlers () from /lib64/libc.so.6
#15 0x00007ffff4736e95 in exit () from /lib64/libc.so.6

chunk=0x1203930)
at
/projects/maplink_ogl_vector/SDK/OpenGLDrawingSurface/core/utility/ringbuffer.cpp:171
The following is reported on the console:
intel_do_flush_locked failed: No such file or directory
The code works on Windows when using NVIDIA and AMD drivers. Not that that is
much help other than to indicate that the code we've written at least works
elsewhere...
I have to return the hardware by the end of the week.</pre>
