    Malloc error

    Hi Group,

    I'm brand spanking new to Python. Never coded in it, but I'm
    comfortable coding in general in other languages. I'm Trying to get
    some legacy code to run on a newer machine. I don't have access to the
    legacy box for debugging.

    I'm getting the following error:

    Python(36979) malloc: *** error for object 0x88374: Non-aligned
    pointer being freed
    *** set a breakpoint in malloc_error_br eak to debug

    My python version is:

    $ python
    Python 2.5.2 (r252:60911, Feb 22 2008, 07:57:53)
    [GCC 4.0.1 (Apple Computer, Inc. build 5363)] on darwin
    Type "help", "copyright" , "credits" or "license" for more information.
    >>>
    And this is on an Intel MacBook running 10.5.2

    The error is getting printed hundreds of times until I CTRL+C at which
    point I see:

    Python(36979) malloc: *** error for object 0xa58074: Non-aligned
    pointer being freed
    *** set a breakpoint in malloc_error_br eak to debug
    Traceback (most recent call last):
    File "v2_to_bdb. py", line 104, in <module>
    main()
    File "v2_to_bdb. py", line 101, in main
    fill_dbm(f, dbm, info, ids, sources)
    File "v2_to_bdb. py", line 34, in fill_dbm
    mystring = stationstring.s erialize(dict, data)
    KeyboardInterru pt

    And advice on how to work around this error will be much appreciated.

    Thanks,

    -k.

      Ouch. I'd like to think that the error doesn't come from Python itself but
      from some compiled C extension. Are you using any?
      I'd try with the same Python version the legacy box had, if it was older
      than 2.5.2

          You're right. I was using some C extensions. The bug was there. I've
          fixed it and everything appears to be working.

          Thanks,

          -k.
