Overwriting as in opening an existing file and rewriting it, rather than replacing it?

I asked about `make install` because I skipped that step; instead I copied directly from the build directory to the install directory.

I you're right about `make install` then we should probably see frequent issues with running applications after updating the installed version that way. Yet that's not my experience, fortunately (I cannot count the number of times I was happy I still had the "original" version running to undo a change...)

Shortly after sending this message I had another KDevelop crash, this time when I started typing in a file in a newly started (and fully idle) session, and deep in Qt's JS code; apparently an allocation went wrong in something called through KTextEditor. That's when I decided I'd better reboot.
Since, I've run `make install` on KDevPlatform with 1 or 2 KDevelop sessions running and they didn't crash. I haven't yet tried to copy a single shlib like before, but I'm crossing my fingers I just had a system instability that didn't mess anything up permanently.

Come to think of it, I don't run `make install` directly to the install directory (/opt/local). Instead it goes through a package manager, so I do something like:
- make install DESTDIR=/path/to/destroot
- cd /path/to/destroot && tar -cjf /path/to/package.tar.bz2 .
- cd / && tar -xf /path/to/package.tar.bz2

AFAIK existing files are replaced, not rewritten when unpacking a tar archive.
