The current commit fixes an invalid memory access which manifests as a random segfault when executing continuous tag read operations. The corruption happens when releasing the memory allocated to a record: in the time between the memory being g_free'd and the subsequent memset operation, the memory could have been reused by some other process. And since memory allocation depends on system-wide factors, it makes this bug hard to track. Tested using ACR122U reader and NTAG213 tags on Automotive Grade Linux (flounder, guppy and master branches) Signed-off-by: Raquel Medina <[email protected]>

which manifests as a random segfault when executing
continuous tag read operations.

record: in the time between the memory being g_free'd and the
subsequent memset operation, the memory could have been reused by
some other process. And since memory allocation depends on
