https://bugs.kde.org/show_bug.cgi?id=3D376870 --- Comment #1 from Rhys Kidd --- Hello Hamish, I've tagged this bug report with the macOS attributes. The missing syscall is proc_rlimit_control(). That is one Valgrind needs to have support added for. macOS 10.12 support is also improving in latest SVN trunk of Valgrind, if you're interested in testing the bleeding edge code. --=20 You are receiving this mail because: You are watching all bug changes.=
