Failure in file-io.cc-tst

[Julien Bect]

Dear Maintainers,

I get the following error in make check (changeset b5bf26a054bd):

>>>>> processing 
/media/data/sources/octave/core/libinterp/interpfcn/file-io.cc-tst
  ***** test
 assert (sscanf ("1,2", "%f", "C"), 1)
 assert (sscanf ("1,2", "%f", "fr_FR"), 1.2)
!!!!! test failed
ASSERT errors for:  assert (sscanf ("1,2", "%f", "fr_FR"),1.2)

     ()           1           1.2        Abs err 0.2 exceeds tol 0


I didn't notice it before, but I can't tell when it started to appear (I 
can bisect later, if that's useful).

Is anyone else but me having this failure ?

I have found two related posts:

http://octave.1599824.n4.nabble.com/New-test-fail-td4310273.html
http://octave.1599824.n4.nabble.com/One-fail-file-io-td4357014.html

but they are more than one year old, with no mention of how the problem 
was solved, and also one (closed) bug report :

https://savannah.gnu.org/bugs/?35364

Let me know if I can help with further testing.
