dMZX Forums: Robotic Copy can copy stale lines -> MegaZeux Bugs -> Tracker

The Robotic editor can copy stale versions of lines in some cases. This is present in 2.92f but also present in the latest GIT (f8f4685).

To easily reproduce, make two lines, copy the first (from the block menu, no marks), paste it in a third line, edit the second line, and copy (block menu, with alt+enter) without leaving the line. It will copy the old contents of the line instead of the current version. For some reason, alt+b will not copy a stale line in this direction set, but it does affect that version of it in other situations not yet pinned down.

This behavior has been seen as far back as 2.80c. It seems to be absent from 2.70, so far.

Here's the segfault I got:

Both issues seem to be corrected (the reliable triggers aren't causing issues anymore).
