segmentation violation with go 1.24 #112
Description
After upgrading go to 1.24 go-graphviz crashes with
unexpected fault address 0xc002400000
fatal error: fault
[signal SIGSEGV: segmentation violation code=0x2 addr=0xc002400000 pc=0x477595]
following with goroutine stack dumps which only contain go runtime paths (no app or lib code involved)
reproduce with this Dockerfile:
FROM golang:1.24
WORKDIR "/app"
RUN go mod init graphviz-crash
RUN go get github.com/goccy/go-graphviz
RUN <<EOF cat > main.go
package main
import (
"context"
"fmt"
"github.com/goccy/go-graphviz"
)
func main(){
gv, _ := graphviz.New(context.Background())
gr, _ := gv.Graph()
gr.CreateNodeByName("test")
fmt.Print("all good")
}
EOF
ENTRYPOINT ["go", "run", "main.go"]
and this command:
docker build --tag graphviz-crash . && docker run -ti --rm graphviz-crash
if you change FROM golang:1.24 to 1.23 it works
