 Sorry for the confusion.  -fno-strict-aliasing was included for
 all compiler alternatives, as per the default.
 
 I.e.:
 	cc -O2 -fno-strict-aliasing    fails
 	cc -O -fnostrict-aliasing      works
 	gcc41 -O2 -fno-strict-aliasing works
 
 It doesn't look like an aliasing bug in the source to me, as the
 gethostname result isn't passed through a variable, let alone
 one that could be dereferenced.
 
 Cheers,
