Thanks very much for Niels and Alon's information!
After double check, I found the strdup triggers Segmentation fault when
-std=c99 included in compiler flags while compile nettle.

However, looking at the code, I believe the allocation of memory is
not required... it can be:
The if (hex_salt) {...} block overwrites the salt storage, for in-place
hex decoding. I don't quite like overwriting the strings passed in via
argv, even if it might be possible. So when I wrote this tool, always
allocating a writable copy, and calling free unconditionally, seemed
nice and easy,
Fair enough :)
