Dear Maintainer, > (On exit is another issue with the FILE structure > in readline library, but saw it just on exit.)
I tried to follow why this crash on exit happens, and found that this second issue is because aeolus does a "fclose (stdin);" on purpose. But libreadline is not prepared to that and raises this error. Just removing that "fclose (stdin);" makes it impossible to close aeolus.
