[Octave-bug-tracker] [bug #57632] 5.1.90 crash on cygwin

[Kai Torben Ohlhus]

Follow-up Comment #9, bug #57632 (project octave):

comment #8 is great news.

Alright, then I think we have the guilty one.  Reduced version of comment #5
program 2:


f = tempname ();
fid = fopen (f, "w");
fprintf (fid, "1\n2\n3\n4\n5\n6");
fseek (fid, 0, "bof");
fclose (fid);
unlink (f);


and


f = tempname ();
fid = fopen (f, "w");
fseek (fid, 0, "bof");
fclose (fid);
unlink (f);


I think any file position manipulation is a serious problem.  This happens
also when calling textscan

Are there any known bugs in cygwin about using fseek, seekg, seekp?
