context release failing

Hello,
I'm using the latest Mali OpenGL ES 3.0 emulator under Ubuntu 12.04 32 Bit with an AMD Radeon HD 6670.
When I try to release the EGL context with this line:

eglMakeCurrent(_eglDisplay, EGL_NO_SURFACE, EGL_NO_SURFACE, EGL_NO_CONTEXT);

I get an EGL error 3003 (Bad Alloc).

Making the context current before was all succesful:

GraphicsWindowX11::init() - eglInitialize() succeded eglMajorVersion=1 iMinorVersion=3
GraphicsWindowX11::init() - window created =1
EGL_SAMPLE_BUFFERS: 1
EGL_SAMPLES: 8
GL renderer: [AMD Radeon HD 6670]
GL vendor:[ATI Technologies Inc.]
GL version: [4.2.12002 Compatibility Profile Context 9.012]
GL shading language version: [4.20]
GL_EXTENSIONS: GL_OES_compressed_ETC1_RGB8_texture GL_KHR_texture_compression_astc_ldr
GL_RENDERER: Mali OpenGL ES Emulator Revision r1p2-00rel0
GL_VENDOR: ARM Ltd.
GL_VERSION: OpenGL ES 3.0
GL_SHADING_LANGUAGE_VERSION: OpenGL ES GLSL ES 3.00

Kind regards,
Alexander Irion

    Hi Alexander,

    What do you mean when you say EGL_OPENGL_ES3_BIT_KHR doesn't work? This token should be accepted by EGL...

    The problem seems to definitely be because EGL_CONTEXT_CLIENT_VERSION and EGL_RENDERABLE_TYPE are mismatched (which may well be a separate problem in our implementation, but I'd need to check further).
