realm-java: Ndk crash in Table.removeColumn. Signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)

Goal

Running a migration removing objects/tables with thousands of instances with cross reference, where first we remove the cross-referencing fields:

schema.getOrFail(“RAirport”) .removeField(“place”)

schema.getOrFail(“RStation”) .removeField(“place”)

schema.getOrFail(“RPlace”) .removeField(“airport”) .removeField(“station”)

And then remove the tables themselves:

schema.remove("RAirport")
schema.remove("RStation")
schema.remove("RPlace")

Actual Results

The first step: removeFields executions are crashing, if occurring then it is hundreds even thousands per user. Native crash reported in play console:

Steps & Code to Reproduce

We can not reproduce it locally, but we got hundreds of reports in play console. It is occurring during a migration to the newest version for some users, usually leading to hundred or thousands of crashes like this per user.

Place and other classes in example are written in java and contain reference to Airport/Station and vice versa.

public class Airport extends RealmObject {
  
  @PrimaryKey
  private String id;

  @Nullable
  private Place place;

   // other stuff

}

public class Place extends RealmObject {
 
  @PrimaryKey
  private String id;

  private Airport airport;
  private Station station;
  // ....

  // other stuff

}

All this is probably not enough to reproduce, as we’re unable to do so locally, but I hope that you’ll have some insights or it can help in other investigations.
