[xmlsec] xmlInitParser() crashes when timer functions are used like CreateTimerQueueTimer()

[Yeshwanth C]

I just debugged the code.
The error occurs at the following locations:-

xmlGenericErrorFunc *
__xmlGenericError(void) {
    if (IS_MAIN_THREAD)
 return (&xmlGenericError);
    else
 return (&xmlGetGlobalState()->xmlGenericError);
}

It goes there from here:-
" if ((xmlGenericError == xmlGenericErrorDefaultFunc) ||
 (xmlGenericError == NULL))" inside xmlInitParser()

Regards
Yesh
