Package: libxslt1.1
Version: 1.1.18-1
Severity: important
When building libxcb, xsltproc 1.1.18-1 segfaults on some of our XML
sources and hangs chewing 100% of the CPU on other sources. I believe
1.1.17-5 was fine. I've heard reports that non-Debian folks building our
code recently starting having this problem too.
The stylesheet we're using is here:
http://gitweb.freedesktop.org/?p=xcb/libxcb.git;a=blob_plain;f=src/c-client.xsl
And the XML documents we're transforming can be found here:
http://xcb.freedesktop.org/dist/xcb-proto-0.9.93.tar.bz2
All of our XML triggers either a hang or a segfault.
You can run the transformation with arguments like these, if you're in
the src directory of the above tarball:
xsltproc --stringparam mode header --stringparam base-path ./ \
c-client.xsl xproto.xml
Processing 'bigreq.xml' illustrates a case where it hangs consuming 100%
of the CPU. From a little fiddling in gdb, I think it's infinite-looping
in xsltReleaseLocalRVTs from transform.c, but I haven't looked at the
source to see if that makes sense.
The cases that segfault have the following stack trace. I can regenerate
it with full debugging information if needed. I'm hoping that Josh
Triplett can help if more than this is needed to debug the problem,
since this XSLT is his code. :-)

Closes: 398327
Changes:
libxslt (1.1.18-3) unstable; urgency=low
.
* libxslt/variables.c: Patch from upstream CVS to fix hangs and segfaults
when processing XCB protocol definitions. Closes: #398327.
* libxslt/transform.c: Added a missing * to the previous patch. No real
problem posed by it missing, but since upstream applied the patch with
it and it's cleaner...
