This is likely to interfere with the workings of Valgrind. As an example of this, Valgrind often needs to open new log files. This may fail if Valgrind has switched user/group/caps. This is more likely to happen if you are running Valgrind on a wrapper script and using the --trace-children=yes. For instance you might be on a system where utilities like 'basename' and 'dirname' are security hardened. If they are used in your wrapper this could result in the problem you are seeing. Alternatively, if you are not using a wrapper, then the best workaround is to have some special Valgrind handling in your executable. See http://valgrind.org/docs/manual/manual-core- adv.html#manual-core-adv.clientreq So you could write some code like if (!RUNNING_ON_VALGRIND) { // your setcap calls } A+ Paul _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
