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
1.mono_jit_init_version
2.mini_init
3.mono_runtime_init_checked
4.create_domain_objects
5.mono_exception_from_name_two_strings_checked
6.create_exception_two_strings
7.mono_runtime_invoke_checked
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.
