I can create a crash by trying to delete the final column in the
following construction:
\begin{align*}
\begin{aligned}\end{aligned}
\\
\end{align*}
To create:
1. Ctrl+Shift+M to create a display math equation.
2. Ctrl+Return to create an align* environment
3. Insert > Math > Aligned Environment in the first (top left) cell
4 Move cursor to the top right cell
5. Try to delete this column
6. Crash. LyX reports " LyX Code: 89 name: mathsplit"
If the aligned environment is placed in the second (top right) cell,
trying to delete the first column causes the crash. Deleting the column
containing the aligned environment does not crash LyX.
There's no data loss. LyX manages to create an emergency file.
