it looks like it is "fop" that is segfaulting. Would you mind checking if this works for you: USE="-java" emerge =dev-haskell/alex-2.0.1-r1 This looks like the same issue as bug #106992 We might have to remove the java USE flag on alex & ghc
I have disabled the java USE flag of the ebuild as a temporary solution until we find a workaround. We think it is a problem of FOP , which version are you using btw? , i am also adding the java herd on the CC so they can be aware of this problem. According to bug #106992 , the same problem happens with ghc6.4.1.
the problem is the stylesheet which fails to create the file fop is supposed to use it does work with app-text/docbook-xsl-stylesheets-1.65.1 but not 1.68something
After doing some tests, we have found that might be problem of libxml2 and libxslt. Which versions are you using?, Could also please update to the latest stable version of both libs if you are not already using them?, i think that should solve the problem. Also, it works fine with the latest app-text/docbook-xsl-stylesheets version, with these updated libs.
I'm using ~amd64, with the following versions of libxml2, libxslt, and docbook-xsl-stylesheets: [ebuild R ] dev-libs/libxml2-2.6.22 -debug +doc -ipv6 +python +readline -static [ebuild R ] dev-libs/libxslt-1.1.15 +crypt -debug +python -static [ebuild R ] app-text/docbook-xsl-stylesheets-1.68.1-r1 dev-haskell/alex-2.0.1-r1 with +doc works; it's already removed the java USE flag, so I didn't bother setting -java. Sorry for the slow reply.
That's very interesting since we were assuming that it would be segfaulting with an older version rather than a newer version. It seems to work when using the latest stable versions of libxml & libxslt.
Perhaps I was unclear, but I said "it works"; is there some reason not in the bugzilla why it's been re-opened?
Well it work now because we disabled the java use flag which controled the creation of pdf documentation using xslt and fop. The bug is really in libxml or libxslt so that's why we've kept this bug open and reassigned it to the text markup team. Actually it's the same problem as bug #106992 so I'll mark it as a duplicate of that one and change that bug's summary to better reflect the cause. *** This bug has been marked as a duplicate of 106992 ***
