Hi Ivan,
the url(http://cr.openjdk.java.net/~igerasim/8202558/00/webrev/ ) is not accessible to me. 

Thanks,

Vyom

I just realized that we've got a similar issue in the same file in the 
function initLocalIfs().


The webrev was updated in place to fix this issue as well.

With kind regards,

Ivan

Hello!


The function needsLoopbackRoute() calls initLoopbackRoutes() to 
initialize two global variables: loRoutes and nRoutes.



If realloc() fails at line 582 then loRoutes is freed, but nRoutes is 
left positive.


Then, in needsLoopbackRoute() the already freed memory will be accessed.

Would you please help review the fix?
