Crash when deleting records with DeleteAllRecords

[Dave Addey]

Hi all,

I¹m getting a crash ­ sometimes, not always, but consistent enough to be a
real problem ­ when using DeleteAllRecords.  Important lines from the crash
log shown below:

I am attempting to delete everything from three tables:

vPlaylistTracks.DeleteAllRecords
vTracks.DeleteAllRecords
vPlaylists.DeleteAllRecords

It seems that is is the second table (vTracks) which is causing the problem.

If it adds anything, I have two vLinks (foreign key links) between the three
tables:

vPT_PlaylistUniqueIDLink = CreateForeignKeyLink("PT_PlaylistUniqueIDLink",
vPlaylists.UniqueID, vPlaylistTracks.PlaylistUniqueIDPtr,
EVOnDelete.kSetNull, EVOnUpdate.kSetNull, false)
vPT_TrackUniqueIDLink = CreateForeignKeyLink("PT_TrackUniqueIDLink",
vTracks.UniqueID, vPlaylistTracks.TrackUniqueIDPtr, EVOnDelete.kSetNull,
EVOnUpdate.kSetNull, false)

I¹m not doing anything to these links before calling DeleteAllRecords
Should I be dropping the links first somehow?
