MemoryError in unnecessary conversion ''.join(chr(c) for c in file_data)

[Denis Kochetkov]

Hello!

Following error occurs often on our build server:

 ...

   File "d:\jenkins\workspace\PAX-2.5.0-agent-win\Sources\Build\pefile.py", line 2187, in write
     new_file_data = ''.join(chr(c) for c in file_data)

 MemoryError
 </Exception>

We use Python 2.7 on Windows 7 SP1. There are many free memory on the server.

The conversion '.join(chr(c) for c in file_data in NOT required when file_data is bytearray. 

bytearray has own string conversion. It works fine and no MemoryErrors occurs. 

I attached patch. It contains replacement of unnecessary conversion on working build-it bytearray conversion. 

Could you please apply attached patch file?

With best regards,
