[Barrelfish-users] bug report about use -O0 compile skb

[Wangjintang]

Hi Kornilios,

	The analyse about this problem is about the same. 
I analyse the stack printf when bug happen, and the the function backtrace, 

lex_an
 fill_buffer
  _local_fill_buffer
    _read_fd
      Read
       Fdtab
         vfsfd_read
           vfs_read

Ringt. I'm using -O0 compile except skb , and it works.
