my go version is 1.13. i used cgo.cstring in my func, and the func will return cstring. i don't know when c complete work about the cstring memory. if i used defer c.free to release the cstring memory, the cstring val will change and return a unexpected value, especially at often apply memory on low memory environment. now i use a funccollect the pointer and release after 1 hour or later. is there any other way to solve?
