[xml] RE: Link error in libxml 2.6.7 on Win32 + crash

[Israel Ganor <ganor softlink com>]

Hi Emanuel,

I compile my C program with  Microsoft Visual Studio 6.0, as a multithreaded
C runtime  DLL (using msvcrt.dll).
I link it statically with libxml_a.lib.
I call xmlReadFile() in the FIRST line of program, so there is no chance of
memory corruption or other effects.
In 2.6.7, this function crashes on Access Violation.

Interesting points:

1. If I call xmlReadFile() with a wrong file name the function returns a
valid error, so basically it is linked correctly.
2. I wrote a simple program that does ONLY xmlReadFile() (on the same XML
file) and exits. 
It is compiled and linked exactly like the real application and with the
same 2.6.7 include files and libraries. 
Amazingly, this test program works fine!
3. My program works fine with 2.6.4.

I'm in a lost. I need 2.6.7 for validating XML vs. schemas.

Thanks in advance
