signrawtransactionwithwallet seems to break the existing signatures of some of the inputs

Bắt đầu bằng cách tái hiện vấn đề với các giao dịch raw trước và sau được cung cấp cùng RPC signrawtransactionwithwallet, sau đó kiểm tra cách các input đã được ký được xử lý khi một input khác được ký. Công việc được hoàn tất khi các scriptSigs hợp lệ hiện có vẫn không thay đổi và RPC không còn báo cáo kích thước stack không hợp lệ cho các input đó.

It seems that this rpc alters the scriptSig of all of the inputs that were already signed (second and third vins in this case), except for the first one.
This is an example with 4 inputs, where the first 3 are transactions that are already signed:

Before executing signrawtransactionwithwallet, I have this transaction:

By decoding both, it seems that this RPC alters the scriptSig of all of the inputs that were already signed, except for the first one.

The error that is returned by the RPC on the inputs that were already signed (second and third vins in this case) is:
"Unable to sign input, invalid stack size (possibly missing key)"
