--- Comment #3 from Kalle Richter <krichter722 at aol dot de> ---
This behavior persists in iconv (Ubuntu EGLIBC 2.17-0ubuntu5) 2.17 if you
choose input file and output file to be the same (maybe only on an x86_64). Did
you one try to reproduce the error with a set of identical input and output
files? If I process the files in the following python script (using temporary
files) everything works fine:
<code>
#!/usr/bin/python

import os
import tempfile
import shutil

# The intention of this script is to avoid error "bus error" when processing
file iconv with identical input and output file

for (dirpath, dirnames, filenames) in
os.walk("/home/richter/sources/Aristoteles", topdown=True, onerror=None,
followlinks=False):
    #print(dirpath, dirnames, filenames)
    for filename in filenames:
        _file = os.path.join(dirpath, filename)
        #print(_file)
        file_ext_pair = _file.split(".")
        if len(file_ext_pair) > 1 and file_ext_pair[len(file_ext_pair)-1] ==
"java":
            _tempfile = tempfile.mkstemp()[1]
            os.system("iconv -f ISO-8859-15 -t utf-8 \""+_file+"\" -o
\""+_tempfile+"\"")
            os.remove(_file)
            shutil.move(_tempfile, _file)
</code>
