failures in /XML_Catalogs-t2c/tests/XML_Catalogs/XML_Catalogs

[Jeff Johnson]

I am getting failures in /XML_Catalogs-t2c/tests/XML_Catalogs/XML_Catalogs. In
dist-checker all 34 subtest fails with

Message from the test:

Target interface(s):
 xmlFreeCatalog
--------
unexpected signal 11 (SIGSEGV) received

Fails on s390x platform only!!!
The problem is in libxml2 library sources shipped with LSB.

# cat test.c
#include <libxml2/libxml/catalog.h>

int main() {
  xmlFreeCatalog(xmlNewCatalog(1));
}
# gcc -I/usr/include/libxml2 -lxml2 test.c
# ./a.out
# gcc -I/opt/lsb/include/libxml2 -lxml2 test.c
# ./a.out
Segmentation fault

I have replaced LSB shipped libraries with libxml2-2.9.0 and rebuilt the test.
It passed:

# ./XML_Catalogs-t2c/tests/XML_Catalogs/XML_Catalogs

Executing tests for XML_Catalogs
..................................
Passed 34 of 34

reproducible also on RHEL-6.3 with libxml2-devel-2.7.6.
