In some cases it is possible for the str() conversion here to throw
encoding errors because log_buf might not point to valid ascii. For
example:
(gdb) python print str(gdb.parse_and_eval("log_buf"))
Traceback (most recent call last):
File "<string>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0303' in
position 24: ordinal not in range(128)
Avoid this by explicitly casting to (void *) inside the gdb expression.
