Double free or corruption when trying a remote execution #5562
Description
Steps to reproduce
I have a VM running, and I'm trying to execute a command remotely with the following command (from a bash shell). It never works (this is for a separate issue that I'll create later), but sometimes powershell even crashes
pwsh -Command - <<EOF
\$Username = '$VM_USER'
\$Password = '$VM_PASSWORD'
\$SecurePassword = ConvertTo-SecureString -AsPlainText \$Password -Force
\$Cred = New-Object System.Management.Automation.PSCredential -ArgumentList \$Username,\$SecurePassword
Invoke-Command -ComputerName $VM_IP -Credential \$Cred -Authentication Basic -Command { $VM_COMMAND }
EOFExpected behavior
The command runs on the remote Windows machine.
Actual behavior
Randomly (maybe once over 4 runs), powershell crashes with a double free. I ran this in strace so it might give a little more information. You'll find in the following attachements a core dump and the stack trace and memory map from the time the double free occured.

Environment data
I don't think it changes anything, but this is run from a Docker container based on ubuntu:xenial, the host system being a debian Jessie with a 4.9 kernel from the backports.
