>Description:
scp(1) from OpenSSH 4.0 fails with:

  xfree: NULL pointer given as argument
  lost connection

when Host definition in ~/.ssh/config includes LocalForward (possibly others)

i noticed today after upgrading yesterday to recent -current, previous
versions (3.x) worked fine.

>How-To-Repeat:
test case:

- create ~/.ssh/config with the following content:

 Host test
  HostName your.host.domain
  LocalForward 10000 localhost:10000

- run scp command:

 scp some.file test:

- see it failing:

 xfree: NULL pointer given as argument
 lost connection

n/a
