Program crashes occasionally with "Segmentation fault" error related to parseUDPSequence() #13

Closed Einslyn closed 1 year ago

Einslyn commented 1 year ago

Our program uses Sick nanoScan3 radar and works fine most of the time. However our embedded system has a small probability of crashing, which is related to this API sick::data_processing::ParseMeasurementData::parseUDPSequence(). The probability of the crashing may be once every 3 days or not.

I haven't pulled the latest code, because the old version has been running very stable. Do I need to update the code?

Is this issue a known issue or has it been resolved?

No warnnings or erros message related to Sick, before the crashing log. Here is the log:

Thank you very much for your reply.

Hi,

please use the updated code. There are always some minor fixes which might improve your experience. Otherwise please provide a stack trace using gdb or similar, to determine where the segfault is happening.

Since this was on older code and there was no update I am closing this. Please open a new issue if the error persists.
