Description
We found that two tables, both associated with the same table and with the same name, were called at the same time when the program was started
err = db.Model(&bo.PeInfo{}).Order("id ASC").Find(&Info1List).Error
There's a probability the program will crash
I tested it on a virtual machine and kept rebooting the program for a minute. There is no problem when I list the association of a table or change the name of the association.
type Info1 struct {
CreatedAt time.Time json:"created_at"
UpdatedAt time.Time json:"updated_at"
Relation []*Relation `gorm:"foreignkey:Id;references:Id"`
}
type Info2 struct {
CreatedAt time.Time json:"created_at"
UpdatedAt time.Time json:"updated_at"
Relation []*Relation `gorm:"foreignkey:Id;references:Id"`
}
The following is the stack information when the program exits
fatal error: concurrent map writes

Error code location, is indeed a map write
if relation.FieldSchema != relation.Schema && relation.Polymorphic == nil && field.OwnerSchema == nil {
relation.FieldSchema.Relationships.Relations[""+relation.Schema.Name+""+relation.Name] = relation
}
and my gorm version：
gorm.io/driver/mysql v1.5.2
gorm.io/gorm v1.25.7-0.20240204074919-46816ad31dde
Thank you very much！
