fatal error: unexpected signal during runtime execution

[dchebakov]

Hi,

Thank you for the project! I'm having some problems to start the application. I'm using golang go1.17.2 darwin/amd64 and right after go run hello.go I'm getting the following error:

$ go run hello.go 
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:   export GIN_MODE=release
 - using code:  gin.SetMode(gin.ReleaseMode)

fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1 addr=0xb01dfacedebac1e pc=0x7fff2046bc9e]

Hey @dchebakov,
I observed the same behavior, but as I'm a golang newbie myself, I can only tell how I made it work, without explaining the reason. Update go-gin to the latest, v1.7.4, as the time of writing these lines, and you should be good to go.
