Description Paul 2013-05-06 17:28:13 UTC 
Hello, I have the following bug. I use Valgrind to debug the iOS Simulator launched by Xamarin Studio.

--66783-- WARNING: unhandled syscall: unix:369
--66783-- You may be able to write your own handler.
--66783-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--66783-- Nevertheless we consider this a bug.  Please report
--66783-- it at http://valgrind.org/support/bug_reports.html.
--66783-- WARNING: unhandled syscall: unix:369

Thank you,
Paul

After some googling, syscall 369 is prlimit64. If it's any help, I installed Valgrind with the argument --enable-only32bit.

I'm launching valgrind as follows from within Xcode:

#define VALGRIND "/usr/valgrind/bin/valgrind"
int main(int argc, char *argv[])
{
    
#ifdef VALGRIND_REXEC
    /* Using the valgrind build config, rexec ourself
     * in valgrind */
    if (argc < 2 || (argc >= 2 && strcmp(argv[1], "-valgrind") != 0)) {
        execl(VALGRIND, VALGRIND, "--leak-check=full", argv[0], "-valgrind -v",
              NULL);
    }
#endif
...
}

Actually, on OS X 10.6+ syscall: unix: 369 appears to be kevent64. We do now support that syscall in Valgrind SVN trunk.

Perhaps you could provide some more details of the specific OS X you are running these programs on when the error reports? And have a test with an SVN trunk version of Valgrind if possible.
Comment 5 Rhys Kidd 2016-12-05 06:50:10 UTC 
Resolving as fixed in Valgrind SVN.

On macOS syscall: unix: 369 (kevent64) has been implemented for >= DARWIN_10_6.

Please reopen if a reproducing test case can be created for modern Valgrind.
