SIGSEGV: segmentation violation on Linux/ARM

Hello, i cross compile a minimal program to run on a board with a Microchip SAM9x60 (ARM926 core) processor. The app only tries to create a single table. The executable crashes and the resulting database file has a size of 0 bytes.

Here are the details to reproduce:

modernc sqlite version: v1.20.3

Go version: go1.20 linux/amd64 (also tested with go1.19.5, same result)

main.go:

package main

import (
	"database/sql"
	"log"

	_ "modernc.org/sqlite"
)

func main() {
	db, err := sql.Open("sqlite", "./foo.db")
	if err != nil {
		log.Fatal(err)
	}
	defer db.Close()

	db.Exec("create table if not exists buffer(item text);")
}

Compiled with: GOOS=linux GOARCH=arm GOARM=5 go build -o sqlitetest main.go

Output when running the executable:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x2c pc=0x23fe8c]

Output of uname -a: Linux 5.15.68-linux4microchip-2022.10 #1 Thu Feb 2 07:33:09 UTC 2023 armv5tejl GNU/Linux The linux system is build with https://buildroot.org/.

As i said, there exists a db file, but with size 0. If i create a valid the db file manually before run, the same error occures.

Any help would be appreciated. Do you need any additional information?
