When I use package syscall like this:

 err := syscall.Mprotect(page, syscall.PROT_READ|syscall.PROT_WRITE|syscall.PROT_EXEC)

error occurs as below

permission denied

It seems EACCES error in C. What should I do?

my MacOS upgraded to Catalina and then caused this problem – Charles Chan Oct 21 '19 at 07:42
Seems like page has read-only flag. – Laevus Dexter Oct 21 '19 at 15:01

Are you using the monkey package? I'm having the same issue. Perhaps you can edit the question to include the package name for people to find this question easier. – z11i Nov 06 '19 at 08:58
