Sat 02 Mar 2024 10:07:40 PM UTC, comment #4: I checked in jwe's changeset on stable here: https://hg.savannah.gnu.org/hgweb/octave/rev/9c08824262af On the development branch, I restored the BIST test that check that the error message is empty: https://hg.savannah.gnu.org/hgweb/octave/rev/2ff2d201a344 This will now produce a failing test on dev.

Mon 05 Dec 2022 04:17:06 AM UTC, original submission: With the current master version self build 9.0 from this Thursday hg log -l1 changeset: 31598:53fee053d962 # HG changeset patch) (s)scanf wrongly duplicates the last value of a string containing multiple values and ending with a space. Without a space at the end there is no duplication. (I guess error is introduced with changeset 31542:2f08a53e0a23) sscanf ('2 3 ', '%f') ans = 2 3 3 sscanf ('2 3', '%f') ans = 2 3	Anonymous
