Update of bug #35910 (project octave):
Status: Patch Submitted => Ready For Test
_______________________________________________________
Follow-up Comment #7:
I ran the test again before applying the patch:
>> tic, for i=1:1e5, string = regexprep('§x', '^(.)', '$1;'); end, toc
Elapsed time is 1.10611 seconds.
>> tic, for i=1:1e5, string = regexprep('§x', '^(.)', '$1;'); end, toc
Elapsed time is 1.09538 seconds.
>> tic, for i=1:1e5, string = regexprep('§x', '^(.)', '$1;'); end, toc
Elapsed time is 1.12862 seconds.
And again with the patch:
>> tic, for i=1:1e5, string = regexprep('§x', '^(.)', '$1;'); end, toc
Elapsed time is 1.1054 seconds.
>> tic, for i=1:1e5, string = regexprep('§x', '^(.)', '$1;'); end, toc
Elapsed time is 1.14079 seconds.
>> tic, for i=1:1e5, string = regexprep('§x', '^(.)', '$1;'); end, toc
Elapsed time is 1.12645 seconds.
Since the performance doesn't seem to be impacted, I went ahead and applied
the patch here:

Marking as ready for test.
