hi,all      I'm doing some research of sgen_cardtable of the embeded mono.
      And find that ,after the mono_jit_init_version call , some bytes of sgen_cardtable is aready setted.
      Some of the call in mono_jit_init_version will call sgen_card_table_wbarrier_set_field to change some bytes of  sgen_cardtable.
      But there is one exception that change the memory of sgen_cardtable without call any of the sgen_cardtable method.
      That exception is the invoke of the  Constructor of System.OutOfMemoryException.
      The Call Chain is 

      I have tested the newest stable release of mono,The result is the same. 

The Quesition is :

    Why call the ctor of System.OutOfMemoryException will cause some byte of  sgen_cardtable be setted without call any method
    of sgen_cardtable.
