Found a BUG with the QB64 editor compiled with the -O3 option

[DSMan195276]

There was a very similar bug in versions before `0.7.0`, so I would check that you're compiling the latest. Also try deleting `./internal/temp/searched.bin` if it exists, that file is what would trigger the bug. Other then that you might have stumbled on some kind of bug when using `-O3`, it would be fairly interesting to me if it was really limited to just the find menu though as I would have expected more general instability.
