The execution recipe works for me on Fedora 28 using valgrind-3.14.0-7.fc28.x86_64.
Also, the default on Mac is to use addresses greater than (1ul<<32).
Because the program works when _not_ run under valgrind, then the conclusion is that valgrind-3.14.0-7 has a bug where it stores an address in 32 bits. To find the bug in valgrind: invoke a debug version of valgrind-3.14 under lldb on Mac, and then invoke main.l.exe under that valgrind. The SIGSEGV should happen inside valgrind itself, so use lldb to find the bug. _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
