Wallet hangs when asked to process several instant sends in quick succession
Summary
I tied to make 5 instant send transactions (to an address not mine) in quick succession. The first 4 reported the txid. On the 5th my (GUI) wallet hung. debug.log shows the first txn went to the correct address, it appears to show the 2-4th txns went to the wrong address. The 5th was going to the wrong address as well.
Steps to reproduce
Make a bunch of instant send transactions in quick succession.
Expected behavior
Transactions get processed, wallet does not hang.
Problematic behavior
Wallet makes 2nd and subsequent payments to the wrong address and eventually hangs.

GUI froze. Killed it with kill -s SIGSEGV.
