I've also tried statically allocated char array on the C side and passing the pointer to it, still no luck, I've also gotten the secondary_stack_ss_allocate() error during runtime, but I cannot adjust the secondary stack size with GNATbind or with library calls to the GNAT secondary stack lib. I want to be able to telnet to the Ada client and just update the ip address, but the only interface exposed to me is the C interpreter for the VxWorks box, so I'm stuck with interfacing with this. I need to set the IP of the broker for the client at runtime, the Ada is the client, and the broker is just on my LAN. I do not know assembly but I imagine this is trying to store the string in a place that is too small? THE ERROR OUTPUT We passed -> 192.168.1.1Įxception current instruction address: 0x002e3ab0Įxamining, the instruction that threw the error 0x2e3ab0 stw r30,8(r9) I can use putty or teraterm for the telnet client if that matters, both throw the same error. I can't figure out why it's throwing a random data access error. When I call the C function SetNewAddrBroker('192.168.1.1') I get a 'data access' error, this is via telnet to the VxWorks machine that this code exists on, the Ada program is the main task, so I know it's not the missing 'adainit() and adafinal()' calls.
