Hello,
I’m getting a panic when calling directory.CreateOrOpen with -race, it appears the memory is 4 byte aligned when golang is expecting it to be 8 byte aligned. This code is a striped down version of class-scheduling-go.html
main.go
package main
import (
// Omitted for having too many links
“log”
)func main() {
fdb.MustAPIVersion(620)
db := fdb.MustOpenDefault()
db.Options().SetTransactionTimeout(60000) // 60,000 ms = 1 minute
db.Options().SetTransactionRetryLimit(100)if _, err := directory.CreateOrOpen(db, string{“scheduling”}, nil); err != nil {
log.Fatal(err)
}
}
