You initialized argument 1 of function Bcd_copysignal with the following constraints:
- The pointer is not NULL.
- The pointer is actually an array with multiple elements.
- The array has max elements.
Assuming ult_ArDstSignalData is that argument 1, your expectation is that the array ult_ArDstSignalData should be accessible at any index. This expectation seems to be correct. Can you show the message that you see for the Illegally dereferenced pointer warning that occurs on line 994?
Also, do you have any warnings in the analysis log that contains the text data-range-specifications?
