[Valgrind-users] massif problem - Unknown option: --undef-value-errors=no

[/ <is...@ya...>]

Hi people, I get the following error when I try to invoke "massif" in 
the most simple manner:

    valgrind: Unknown option: --undef-value-errors=no
    valgrind: Use --help for more information or consult the user manual.

Command to reproduce the error:

    valgrind --verbose --tool=massif executable

where executable was the program i wanted to check (compiled with -g)

even a simple

    valgrind --verbose --tool=massif /bin/bash

produces the same error

** Valgrind version:
valgrind-3.14.0

Fedora, linux 4.18.19-100

Many thanks,
a.
