Re: bug in lang/perl5 5.18.0?

On my amd64 6.99.19 box: 
perl-5.18.0/t % LD_LIBRARY_PATH=.. ../t/perl  -I.. -MTestInit=U2T 
re/fold_grind.t 2>&1 | grep -v '^ok'
1..467

(i.e. they all succeed)

on my i386 5.1_STABLE box:
perl-5.18.0/t % LD_LIBRARY_PATH=.. ../t/perl  -I.. -MTestInit=U2T re/fold_grind.
t 2>&1 | grep -v '^ok'

I suspect the next thing to do is to recompile with -O instead of -O2,
especially for the Encode/ and cpan/Encode bits.
