test result of fbo
(In reply to comment #3)
But I find it failed from 20080826, the day GL_EXT_framebuffer_object was supported. Before that it was not supported.
OK, we don't really expect bug reports for always-failing testcases at this point -- our priority is regressions and improving issues that are impacting applications.
This was a bug in the testcase when handling an unsupported framebuffer in a previous test. Yet another reason why you should never build tests that test more than one thing at a time.

glean/tfbo: Properly clean up when the driver reports unsupported.
Fixes spurious test failures on the intel driver.
It still fails on Pineview now with the same error info as following.

some more info is I tested it with both the glean source contained in piglit test and the glean source from glean.git.sourceforge.net.
