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

[Yeshwanth C]

It appears that if the thread is switched to some other thread, these calls
to libxml2 all fail.
Because when I ran the same code in a loop and checked the thread id, for
successful runs, the thread ids were all the same.
Could you tell me some way how to switch the thread back to the original
thread before calling these methods? or suggest some other solution?
