Sorry, I forgot to attach the referenced files. So here the attachments. 2015-07-23 13:24 GMT+02:00 Björn Kautler <bjo...@kautler.net>: > Hi, > > because there were often stack overflow errors on Windows with xmllint > (exit code 0xC00000FD), I updated our used version from 2.7.8 (with > iconv 1.9.2 and zlib 1.2.5) to 2.9.2 (with iconv 1.14 and zlib 1.2.8). > > But by doing this, I found some different behaviour in the two > versions about which I'd like to check back here whether this is > expected behaviour or bugs. > > We use xmllint in our toolchain for building DocBook roughly in the > following way: > > - Use xmllint to resolve XIncludes (xmllint is the only option, as we > use the xpointer()-scheme) > - Here it is expected that various IDs are used mutliple times and > that various IDREF attributes reference unknown IDs > - Do some profiling for various attributes, like customer, enabled > features for the build etc. with XSLT > - Now if the profiling attributes were set correctly by the docu > team, the XML should be valid without double IDs and without dead > links > - Use xmllint with "--postvalid --noout" to make sure the profiling > attributes were set correctly > - Do the DocBook transformations > > > Here the four things I recognized so far: > > 1.
