k command does not display some managed frames

[gitvron]

k command shows method names for most managed frames in mixed callstacks. But for some modules it fails. The frames are displayed as raw addresses instead of method names. Ex:

0:000> kpn

Run .reload /f command and then run k again and it displays the symbol for that frame:

0:000> kpn
 # Child-SP          RetAddr               Call Site

Is this a bug in the k command? Or issue with the module?

@lzybkr Does k command have full support for mixed C++ & C# callstacks?
