Bus error when using mmap

[Roman Suzi]

When trying to write beyond EOF (of original file) in mapping of mmap I
receive BUS ERROR. Interpreter just quits. While it is understandable,
maybe some safety checks could be done in mmap methods to prevent such
unstable behaviour?

This is offending piece:

Python 2.1 (#1, Sep 24 2001, 23:22:13)
[GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> import mmap
>>> f = open("eee", "w+")  # !!! zero size, should be "r+", but:
>>> mm = mmap.mmap(f.fileno(), 100)
>>> mm[0:10] = "*"*10
Bus error


Sincerely yours, Roman Suzi
