static bool ProgramCounterToHumanReadableString
(

Remarks

Converts the passed in program counter address to a human readable string and appends it to the passed in one.

: The code assumes that HumanReadableString is large enough to contain the information.

: Please, do not override this method. Can't be modified or altered without notice. This method is the same for all platforms to simplify parsing by the crash processor.
