Package to remove nil pointer errors from your Go programs

nosigsegv

Remove nil pointer problems from your go program!

Usage

If you are running a recent Linux version, you need to run the following command before using nosigsegv.

sudo sysctl -w vm.mmap_min_addr=0

Now nil pointers are not going to crash your program anymore.

Example

Add the following line at the top of your go program:

import _ "github.com/thebabush/nosigsegv"

For a complete example, see cmd/nosigsegv/main.go.

Test it yourself:

$ cd ./cmd/nosigsegv
$ go build
$ ./nosigsegv
initialization ok!
testing...
* <nil>  =  123

Limitations

• Only works on Linux
• Does not support pointer values other than nil, unless there's already something allocated at that address
