Dear Alexander,

 

I also ran your script after applying patches on REL_14_STABLE, but I got another failure.

I have not analyzed yet so I share the result as-is.

Was I missing something?


```

#0  0x00007f4f033de387 in raise () from /lib64/libc.so.6

#4  0x00000000008dfae8 in ReorderBufferTXNByXid (rb=0x19a95c0, xid=1753, create=true, is_new=0x0, lsn=37430336,

Yes, you're right. That script produces another failure as I mentioned
upthread, but still in AssertTXNLsnOrder().
I had thought that the fix should cover that case too, but then I found out
that the defect in question is rather new, so maybe the more focused fix is
really preferable.

Best regards,
Alexander
