Bug#320059: xvfb: SEGV in XCopyPlane() triggered by VSW4 test suite (part of LSB 3.0 certification suite)



Package: xvfb
Version: 4.3.0.dfsg.1-14
Severity: important
Tags: upstream fixed-upstream

Xvfb has a bug in it that is tickled by the VSW4 test suite.  One of the
tests in that suite (/tset/CH06/cpypln/cpypln 3), now enabled as part of
the LSB 3.0 conformance checks, causes xvfb to SEGV in XCopyPlane().

Jeff Licquia tells me that the Xvfb from X.Org X11 6.8.1 fixed this
problem; it should therefore be possible to borrow a patch from
freedesktop.org CVS or the X.Org X11 6.8.2 packages to fix this.

We may want to try to push this fix into a stable-update release for sarge;
while not in itself an LSB test failure, it does make using Debian Sarge
itself as a platform for testing LSB conformance significantly more painful
than it should be.  Jeff says this is actually "vital" for demonstrating
the LSB conformance of Sarge, assuming our other (relatively few)
LSB-related problems are resolved.

(This is not a problem for LSB 2.0, because that version's conformance test
suite switches this test off.)

CCing Matt Taggart so that he knows to flag this as a Sarge LSB issue.
