Hi all,

thanks to @Ben Wiley's instruction, I've finally managed to install Valgrind on
OSX 10.13.2 (17C205).
When I try to execute it, I get the following message :

==28351== Memcheck, a memory error detector

SyscallStatus *, SyscallStatus *)): the 'impossible' happened.

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.

If that doesn't help, please report this bug to: www.valgrind.org

In the bug report, send all the above text, the valgrind
version, and what OS and version you are using.  Thanks.

Hope it can helps...
