[Octave-bug-tracker] [bug #54180] libinterp/corefcn/file-io.cc-tst failure and weird output when test suite is run twice

[Dan Sebald]

Follow-up Comment #4, bug #54180 (project octave):

I made a little mod to the scripts/testfun/__run_test_suite__.m (attached)
which will run file-io.cc-tst after every test.  I wanted to see exactly at
what point file-io.cc-tst starts failing.

Throughout the whole test suite there is no file-io.cc-tst fail on the first
pass.  On the second pass, it starts failing immediately:


  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90
  time/is_leap_year.m ......................................... PASS      6/6
  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90
  time/now.m .................................................. PASS      4/4
  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90
  time/weekday.m .............................................. PASS    
20/20
  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90

Fixed test scripts:

  bug-35448.tst ............................................... PASS      2/2
  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90
  bug-35881.tst ............................................... PASS      1/1
  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90
  bug-36025.tst ............................................... PASS      1/1
  libinterp/corefcn/file-io.cc-tst ............................ PASS    
90/90

 PASS     89/90


I believe there are one or two missing "fclose()" calls in the io.tst.  I've
made some changes and started rerunning the test.  If it works I'll post a
changeset.
