             Summary: avro-c: possible crash error in codec cleanup code
                 Key: AVRO-1115
                 URL: https://issues.apache.org/jira/browse/AVRO-1115
             Project: Avro
          Issue Type: Bug
          Components: c
    Affects Versions: 1.7.0
            Reporter: Pugachev Maxim
            Priority: Critical


There is a possible crash error in codec cleanup code. Test-case is simple: you 
need to call an "avro_file_writer_open" function with wrong file name (i.e. 
non-existent file). Valgrind output:

==15259== Conditional jump or move depends on uninitialised value(s)
