[xml] 2.9.4 SEGV in testsuite on Solaris 10

[Albert Chin <libxml mlists thewrittenword com>]

I've built libxml-2.9.4 on Solaris 10 with the Sun C compiler and
the testsuite is giving a SEGV:
  $ gtar zxf libxml2-2.9.4.tar.gz
  $ cd libxml2-2.9.4
  $ ./configure CC=cc CFLAGS="-g -xs" --disable-shared \
    --disable-silent-rules --without-python
  $ gmake
  ...
  $ gmake check
  ...
  [ -d test   ] || ln -s ./test   .
  [ -d result ] || ln -s ./result .
  ./runtest &&  ./testrecurse && ./testapi &&  ./testchar&&  ./testdict
  &&  ./runxmlconf

Any ideas?
