Tkx for the fast answer and fix, but the error remains the same ...

The error occurs every time I run makedepend, is quite deterministic, so
it should be easy to find out some unexpected problem due to some unusual
sequence of syscalls of makedepend. Please look at the attached trace of
the makedepend command that triggers the arlad assert. The exact command
was "makecommand -f deps ../client.c". As you can see, the file "client.c"
is not relevant at all to this problem since arlad dies during the
manipulation of file "deps" by makedepend. The file "deps" belongs to an
AFS volume.

Hope this helps.

Best regards,

    André
