Move Context::sync to Display::sync. This is a workaround for an Intel bug. The crash looks like this: 0x5f816c53 [d3d9.dll + 0x00036c53] CQuery::~CQuery() 0x5f816bec [d3d9.dll + 0x00036bec] CQuery::`vector deleting destructor'(unsigned int) 0x5f7e8129 [d3d9.dll + 0x00008129] CBaseObject::~CBaseObject() 0x5f9e19c7 [libglesv2.dll + 0x000319c7] gl::Fence::`vector deleting destructor'(unsigned int) 0x5f9de78e [libglesv2.dll - context.cpp:975] gl::Context::deleteFence(unsigned int) 0x5f9e1491 [libglesv2.dll - context.cpp:198] gl::Context::~Context() 0x5f9e182f [libglesv2.dll - context.cpp:3936] glDestroyContext 0x717654ec [libegl.dll - display.cpp:749] egl::Display::destroyContext(gl::Context *) 0x7176a3da [libegl.dll - libegl.cpp:907] eglDestroyContext 0x64fbaf33 [chrome.dll - gl_context_egl.cc:75] gfx::GLContextEGL::Destroy() This is a crash in deleteFence but the same could happen in flush. Fix for the former to follow. The vendor ID is always 8086 (Intel). Not an XP issue - it's happening on Win 7. Tested by stepping through a call to glFinish in the debugger and ensuring that it sleeps but eventually returns.
