libxl: xl crashes

libxl: xl crashes

[Christoph Egger]

Hi,

xl crashes very early.
To repeat just run 'xl list' or 'xl create'

(Yes, 'xl create' w/o specifying a config file)


The line where the crash happens was last modified in changeset 
21000:3138b3885999.

Core was generated by `xl'.
Program terminated with signal 11, Segmentation fault.

Reverting the changesets 22733:0b04aea87667, 22734:1434b8515233 and 
22735:cb94dbe20f97  brings xl back to function.

I can confirm that c/s  22738:20b0f709153e fixes this.

Thanks, and for the report.  Sorry about that.  I think I fat-fingered
something when applying my own patch series ...

Ian.
