[Xen-devel] [TESTDAY] xl cpupool-create segfaults if given invalid configuration

[George Dunlap <dunlapg@xxxxxxxxx>]

# xl cpupool-create 'name="pool2" sched="credit2"'
command line:2: config parsing error near `sched': syntax error,
unexpected IDENT, expecting NEWLINE or ';'
Failed to parse config file: Invalid argument
*** glibc detected *** xl: free(): invalid pointer: 0x0000000001a79a10 ***
Segmentation fault (core dumped)

Looking at the code in xl_cmdimpl.c:main_cpupoolcreate() it calls:
* xlu_cfg_init()
* xlu_cfg_readdata()

if the readdata() fails, it calls xlu_cfg_destroy() before returning.

Other callers to readdata() seem to call exit(1) if readdata() fails.

So is readdata() leavnig the config in an inconsistent state?  Or is
config already cleaned up?
