Dear Sirs,
this is CentOS Linux release 7.4.1708 (Core) /
3.10.0-693.11.6.el7.x86_64 kernel / gcc (GCC) 4.8.5 20150623 (Red Hat
4.8.5-16).
I tried to use two recent versions of valgrind, the most current GIT (as
of today) and then the last release (3.13.0).
Both versions refuse to run "valgrind --tool=exp-sgcheck" in the same
way (I also tried to completely disable SELinux, if that matters):
----------------------------------------------------------------------
[...]$ valgrind --tool=exp-sgcheck /bin/ls
==20624== exp-sgcheck, a stack and global array overrun detector

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.
----------------------------------------------------------------------
I haven't found any hints in the documentation about such an issue.
Could you, please, help me,
Best regards,
Jacek.
