runtime: cgo using programs have a goroutine marked [syscall, locked to thread]; #17384
Please answer these questions before submitting your issue. Thanks!
What version of Go are you using (
This is what you will see if the C code you are calling dereferences a NULL pointer at PC 0x7fff823874cc. Use the debugger to find the function at that address. The "syscall, locked to thread" is normal for a signal that occurs during a cgo call. Closing because there is no obvious Go problem. The fact that it works on other systems does not mean that it works on Mac OS. If you are convinced there is a Go problem, please tell us precisely how we can reproduce the problem ourselves.
