Re: relearning C: why does an in-place change to a char* segfault?

"this is a test" is a string literal, and is typically part of the
program's image.  (There are some C implementations that do things
differently, like storing such initialisation data in a compressed
format.)

What implementations do that?  Typically data that's all zeros isn't
stored in the image, but general compression isn't something I've seen
(not that I've paid much attention).  It would save space in the image,
but it would require decompression at load time and wouldn't save any
space at run time.
