           Summary: OOM running
                    webgl/sdk/tests/conformance/context/context-creation-a
                    nd-destruction.html
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tomeu at tomeuvizoso.net

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.
