[xml] Problem under HPUX 11.00 and SUNOS 5.8 with static library

[regis chedmail mpsa com]

I have some problems with libXml2-2.6.2 under HPUX 11.00 (with cc 11.11.02)
and under SUNOS 5.8 (whith cc 6.1.45)

Problem only with static library libxml2.a and not with shared library
No problem under HPUX 10.20 with cc 10.32.30
No problem under AIX 4.3.3 with xlc

I have a bad XML like this :

<?xml version="1.0" encoding="ISO-8859-1"?>
<BASE>
data
</Base>


I use the function xmlParseFile() in my program.
under HPUX 10.20 and AIX 4.3.3, there is an error :
local/e206195/Test5.xml:4: parser error : Opening and ending tag mismatch:
BASE line 2 and Base
</Base>
               ^

OK but under HPUX 11.00 or SUNOS 5.8
=> coredump

-> Debugger informations with dde under HPUX 11.00 :

xmlGenericErrorDefaultFunc(ctx=00000000,msg=00129ED8,*msg="%s:%d: ")

I'm a beginner with libxml2, so if someone can help me ?

thanks,
