Re: [ptp-user] PTP hangs debugging local job after throwing an exception
|
I’ve spent some time looking into this, but it’s hard to see what the exact cause could be as it happens while decoding a compressed packet. It could be an error in the decompression algorithm, something like an architectural difference between the client and server side of the debugger, or an old version of the SDM. Does it happen in the same place for the same executable every time? Can you provide a test case that triggers the problem?
