RE: [xml] Problem running testapi for libxml2

[<ABeylin axsone com>]

Hello Daniel, thank you for the quick reply.

On Sun, with the snapshot's source "testapi" still creates core, stack
is attached below.
On HP, compilation fails with snapshot's source code, failure is
attached below.
On AIX, the tests worked successfully, but for fun I attached the stack
trace from the version 2.6.16

Here's compilers I am using:
HP-UX: 3.3.2
Sun: 3.3.2
AIX: 3.3.1


We are currently trying to port to libxml.
We are building commercial software, and need to use a stable release of
libxml.
Our preference is to build libxml ourselves, instead of downloading
pre-built binaries. 
How do I build a stable version on HP-UX/Sun and AIX platforms?  It has
to be a versioned version (not snapshot).  Are any compilers or versions
of compilers recommended?

  xmlRegisterCharEncodingHandler message, yes, I didn't silent it yet.
Now if you manage to crash testapi on some compilers/platforms, it's
great
the goal of testapi is to try to crash the library code by abusing
the API as much as possible. First make sure you have the latest version
(grab the snapshot dist from ftp://xmlsoft.org/), then with your
debugger
gdb/dbx/... run testapi, and show us the stack trace, there should be
a test_xmlXXXX() function calling xmlXXXX() which led to the crash.
And that is important.

  We already got a testapi report which was fixed by William Brack
on CVS, so please try with the libxml2-snapshot.tar.gz version and
tell us if it still crashes.

 thanks,

Daniel
