[xml] libxml2-2.7.7/doc/examples test suite failure on ia64 (parse2 test2.xml)

["Mark Lavi" <mlavi sgi com>]

Hello everyone:

 

I have a test suite issue from LibXML2 2.7.7 on ia64 (SuSE Linux 9.2), I have reviewed Bugzilla and the mailing list archives since it's release. I do not have the issue on x86-64 with SuSE 10.2.

 

make tests ends with:

## Module tests
Success!
make[1]: Entering directory `/src/build/dev/20100427/libxml2-2.7.7/doc/examples'

make[1]: *** [tests] Error 139
make[1]: Leaving directory `/src/build/dev/20100427/libxml2-2.7.7/doc/examples'
make: *** [tests] Error 2

Of course, I can reproduce this when I:

$ cd doc/examples

$ make -f Makefile tests

When I remove the @ from tests section in the makefile and then rerun the above, I see this tail:

> test1.xml: Processed ok
> test2.xml: Processed ok
> test3.xml: Processed ok
(grep "MORY ALLO" .memdump  | grep -v "MEMORY ALLOCATED : 0" ; exit 0)
( ./parse2 test2.xml)
make: *** [tests] Error 139

I believe I've isolated the error to a segmentation fault. With LD_LIBRARY_PATH environment variable empty, I check and then run parse2 in the doc/examples/ directory after I figured .libs/parse2 needed help. You can see that it links against zlib 1.2.4 in /data/20100427/lib:

 

$ LD_LIBRARY_PATH=.libs:../../.libs ldd .libs/parse2
 linux-gate.so.1 =>  (0xa000000000000000)
 libxml2.so.2 => ../../.libs/libxml2.so.2 (0x2000000000044000)
 libdl.so.2 => /lib/libdl.so.2 (0x20000000002f4000)
 libz.so.1 => /data/20100427/lib/libz.so.1 (0x200000000030c000)
 libm.so.6.1 => /lib/tls/libm.so.6.1 (0x2000000000348000)
 libc.so.6.1 => /lib/tls/libc.so.6.1 (0x20000000003fc000)
 /lib/ld-linux-ia64.so.2 (0x2000000000000000)

$ LD_LIBRARY_PATH=.libs:../../.libs ./parse2 test2.xml
Segmentation fault

Can anyone help me figure out how to troubleshoot this further? I realize I can skip these tests, but this is new in 2.7.7 on ia64 and did not happen on the same platform with libxml2-2.7.6 and zlib-1.2.3. I could try to build with zlib 1.2.3 to confirm if it is the culprit?
