I've recently had the problem that FILE_TEST reports a file unreadable, even though every other indication is that it is. Has anybody else seen this kind of behaviour for FILE_TEST?

IDL> file = DIALOG_PICKFILE()
IDL> print, file
/some/dir/file.xx
IDL> print, FILE_TEST(file)
1
IDL> print, FILE_TEST(file, /REGULAR)
1
IDL> print, FILE_TEST(file, /REGULAR, /READ)
0

And yet

IDL> xdisplayfile, file

shows the contents of the file.

The pathname does contain some symbolic links.

IDL 5.4 (OSF alpha)
