Indeed, the old buffer is freed before being copied.

Yep, this isn't a regression. In fact, with 4.4.3 it was the /empty string/
having the size of 1 in the comment#0 testcase, so bug#40518 actually improved
things here.

However, doesn't any operation with (const _CharT*, size_type) as input
parameter potentially have a problem with ( own.c_str(), own.size()+1 ) ?
