If you are using ddrescue against a filesystem (to recover raw file

Do you mean recovering a file from a damaged filesystem (mounted
read-only I hope), as in the following command?
ddrescue /somedir/somefile outfile logfile
Neither ddrescue nor the kernel should segfault in such scenario. What
versions of ddrescue and OS are you running? What type of filesystem?
I'd like to see two (what I see as probably relatively simple)
improvements to alleviate this:
They are not so simple. So I would like to be sure that they are useful
before trying to implemente them.
1. Implement a "--log-every-time" option - you could use "-e" it
The '-e' option is already taken since version 0.1 (2004). You are using
GNU ddrescue. Aren't you?
