  SVN rev 184290 on 2008-10-26 15:41:23Z by kib
  
  MFC r184060:
  Ktr(9) stores format string and arguments in the event circular buffer,
  not the string formatted at the time of CTRX() call. Stack_ktr(9) uses
  an on-stack buffer for the symbol name, that is supplied as an argument
  to ktr. As result, stack_ktr() traces show garbage or cause page faults.
  
  Fix stack_ktr() by using pointer to module symbol table that is supposed
  to have a longer lifetime.
