We are having a critical issue with the libnfc-nci library. The nfcDemoApp application runs into a segmentation fault and crashes intermittently after it detects an NFC tag. I believe the crash happened during nfcTag_readNdef() function call. We are using Linux kernel 4.9.87 and nci library Rev 2.4 with the patch you provided to us last time. We had same issue with nci library Rev 2.2. Attached is the application log as well as debugger log .
Thank you and look forward to hearing from you soon.
