           Summary: memory leak in cnexus.c
           Product: Biopython
           Version: 1.52
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Main Distribution
        AssignedTo: biopython-dev at biopython.org
        ReportedBy: jheled at gmail.com

There seem to be a serious leak in cnexus. The python documentation says,

  When memory buffers are passed as parameters to supply data to
     build objects, as for the `s' and `s#' formats, the required data
     is copied.  Buffers provided by the caller are never referenced by
     the objects created by `Py_BuildValue()'.  In other words, if your
     code invokes `malloc()' and passes the allocated memory to
     `Py_BuildValue()', your code is responsible for calling `free()'
     for that memory once `Py_BuildValue()' returns.
