    xmlParserError calls the xmlGenericError routine which is initialized
to xmlGenericErrorDefaultFunc, with the default xmlGenericErrorContext which
is initialized to NULL.

  So that call is correct. 
  BUT xmlGenericErrorDefaultFunc() code is:

---------------
void
xmlGenericErrorDefaultFunc(void *ctx ATTRIBUTE_UNUSED, const char *msg, ...) {
    va_list args;

    if (xmlGenericErrorContext == NULL)
	xmlGenericErrorContext = (void *) stderr;

    va_start(args, msg);
    vfprintf((FILE *)xmlGenericErrorContext, msg, args);
    va_end(args);
}
---------------

  Unless stderr == NULL in Solaris which would be really really strange,

>  0x1646c8)

  I really don't see how the first argument to vfprintf being passed can be
NULL !

  I really don't know there is something really really strange here !

  Take a debugger and check by single stepping, possibly looking at
the assembly generated. I don't understand how the first argument of the
call can be NULL ! Or someone else on Solaris can reproduce your problem
and check it for you, sorry I can't ...
