如何在OS X上的Go程序中计算系统调用？

Question

I'm trying to count the syscalls in my Go program on OS X Yosemite. I've tried using dtruss and dtrace, but both cause my program to crash with the following error, followed by a stack trace:

fatal error: runtime: bsdthread_register error

The two commands I've used are:

1. sudo dtruss "./my_program my_arg"
2. sudo dtrace -c "powerset 2" -n 'syscall:::entry { @num[probefunc] = count(); }'

Things I've Tried

The main takeaway from my Google-foo has been to unset DYLD_INSERT_LIBRARIES, which I have done numerous times to no avail.

./my_program is a binary that I created with go install. I've written an equivalent C program and both of the above commands work fine with that.

If you want to use dtrace on macOS, you will need to use the external linker to build your program

-ldflags -linkmode=external
