Bug 80509

Running the test at https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/context/context-creation-and-destruction.html causes the process to run out of memory and ultimately crashes in the GL driver. Wonder if it's related to #76225. This is with the HEADs of both WebKit and Mesa. gdb --args ./Programs/GtkLauncher --enable-webgl=1 https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/context/context-creation-and-destruction.html Mesa: User error: GL_OUT_OF_MEMORY in glTexImage Mesa: User error: GL_OUT_OF_MEMORY in glTexImage2D Mesa: User error: GL_OUT_OF_MEMORY in glTexImage Program received signal SIGSEGV, Segmentation fault. 0xaaf85425 in st_validate_attachment (ctx=0xc51e5f8, screen=0x8323418, att=0xc547910, bindings=2) at state_tracker/st_cb_fbo.c:446 446 format = stObj->pt->format; (gdb) bt #0 0xaaf85425 in st_validate_attachment (ctx=0xc51e5f8, screen=0x8323418, att=0xc547910, bindings=2) at state_tracker/st_cb_fbo.c:446 #1 0xaaf8571f in st_validate_framebuffer (ctx=0xc51e5f8, fb=0xc547730) at state_tracker/st_cb_fbo.c:544 #2 0xaaed29fa in _mesa_test_framebuffer_completeness (ctx=0xc51e5f8, fb=0xc547730) at main/fbobject.c:864 #3 0xaaed5136 in _mesa_CheckFramebufferStatusEXT (target=36160) at main/fbobject.c:1884 #4 0xb603d90d in WebCore::GraphicsContext3D::reshapeFBOs (this=0xc479e00, size=...) at ../Source/WebCore/platform/graphics/opengl/GraphicsContext3DOpenGL.cpp:120 #5 0xb603e7ee in WebCore::GraphicsContext3D::reshape (this=0xc479e00, width=2048, height=2048) at ../Source/WebCore/platform/graphics/opengl/GraphicsContext3DOpenGLCommon.cpp:239 #6 0xb6012aa7 in WebCore::WebGLRenderingContext::initializeNewContext ( this=0xc547a68) at ../Source/WebCore/html/canvas/WebGLRenderingContext.cpp:514 #7 0xb6012505 in WebCore::WebGLRenderingContext::WebGLRenderingContext ( this=0xc547a68, passedCanvas=0xc47b150, context=..., attributes=...) at ../Source/WebCore/html/canvas/WebGLRenderingContext.cpp:446 #8 0xb6012163 in WebCore::WebGLRenderingContext::create (canvas=0xc47b150, attrs=0x8fccee0) at ../Source/WebCore/html/canvas/WebGLRenderingContext.cpp:415 #9 0xb59f5408 in WebCore::HTMLCanvasElement::getContext (this=0xc47b150, type=..., attrs=0x8fccee0) at ../Source/WebCore/html/HTMLCanvasElement.cpp:197 #10 0xb56873a0 in WebCore::JSHTMLCanvasElement::getContext (this=0xac61cd80, exec=0xac0401e8) at ../Source/WebCore/bindings/js/JSHTMLCanvasElementCustom.cpp:75 #11 0xb617e9d8 in WebCore::jsHTMLCanvasElementPrototypeFunctionGetContext ( exec=0xac0401e8) at DerivedSources/WebCore/JSHTMLCanvasElement.cpp:208 #12 0xac632f29 in ??
