Follow-up Comment #6, bug #51950 (project octave):
Here is an exact test case for someone to investigate with:
A = sparse ([1, 3, 5], [2, 3, 6], ...
[ 0.03535703796050893, ...
-0.094869220215099748, ...
0.1570058435544345]);
[~, R] = qr (A); ## ← this returns bad R with OOB elements
qr (R) ## ← this crashes
