Stack Overflow caused by managed code is manifested as Stack Overflow (User Mode) with JIT Code recursive entries. !CLRStack WinDbg SOS extension command may work for very long if stack frame are small so we may need to increase the number of frames to show (.kframes command) and then manually check the originating frames using !IP2MD SOS extension command.
