            Bug ID: 91433
           Summary: piglit: fbo-depth copypixels GL_DEPTH_COMPONENT32F
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965

          Reporter: imirkin at alum.mit.edu
        QA Contact: intel-3d-bugs at lists.freedesktop.org

This is triggered on a HSW (no idea about other hardware):

$ bin/fbo-depth copypixels GL_DEPTH_COMPONENT32F -auto
...
Mesa 10.7.0-devel implementation error: Incorrectly writing swrast's integer
depth values to MESA_FORMAT_Z_FLOAT32 depth buffer
Please report at https://bugs.freedesktop.org/enter_bug.cgi?product=Mesa

nouveau and radeonsi appear to cope with this just fine.
