This is an issue happening on radeonsi after the commit6f8e6fb99c"mesa/st: use compute pbo download for readpixels". This commit enables a new code path which has this memory leak. For instance, this issue is triggered on radeonsi with "piglit/bin/glsl-fs-raytrace-bug27060 -auto -fbo": Too many leaks! Only the first 5000 leaks encountered will be reported.
