go-processing string causes memory overflow

This is a creation in Article, where the information may have evolved or changed.

Today with go to do the character "+" connection operation, each connection string roughly about 10M, loop connected 100 times, directly caused the go memory overflow.

//Text Project Main.goPackage Mainimport ("Io/ioutil"    "Log"    "OS") Func main () {log. Println ("Start") UserFile:="D:\\txt\\2.txt"    //Read the fileReadbuf, _: =Ioutil. ReadFile (UserFile)//Word Data processingLog. Println ("Start processing Data") Strcontent:=string(READBUF) forI: =0; I < -; i++{strcontent+ = Strcontent +"Gas Money"} log. Println ("end of data processing") BUF:= []byte(strcontent)//Write a fileIoutil. WriteFile (UserFile, buf, OS. modeexclusive)}

The reported exception:

Runtime:out of Memory:cannot Allocate 335872000-byte block (998440960 in use)

Fatal error:out of Memory

The same business logic with NET to handle is normal operation, there is no memory overflow situation, it seems golang garbage collection and content distribution is not mature enough, need to strengthen
