[Octave-bug-tracker] [bug #63383] Error in sscanf in special cases when '%f' conversion is used

Follow-up Comment #2, bug #63383 (project octave):

what I think is a position error with '%d' in the following example:

Mmmm, in my case Octave returns:

>> [val, count, msg, pos] = sscanf ('1 2 3 -', '%d')
val =

   1
   2
   3

count = 3
msg =
pos = 8

The error message is not set. I'm running Octave 7.3.0 compiled by myself in
Debian Sid

On the other hand, Matlab 9.2.0.538062 (R2017a) returns:

>> [val, count, msg, pos] = sscanf ('1 2 3 -', '%d')
val =
     1
     2
     3
count =
     3

msg =
    'Matching failure in format.'

pos =
     7
