            Bug ID: 137485
           Summary: Double load with symlinks - missing 'realpath'
           Product: LibreOffice
           Version: 6.4.7.2 release
          Hardware: All
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: framework
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: michael.meeks at collabora.com

I run:

soffice ~/foo.odp

my home is symlinked thus:

/home/michael -> ../crypt-home/michael

If then run:

strace -f -e file -o /tmp/slog loffice ~/foo.odp  /crypt-home/michael/foo.odp 

It can be seen that I load the same file twice - which is a horror - and leads
to data-loss =)

Did someone try to optimize the 'realpath()' code or something ? interestingly
the second load seems to walk back the elements of the path following symlinks
as I would expect to try to detect duplicates.

I believe this is a regression; also data-loss ... on Linux.
