zlib compress and uncompress on bit string << 255, 3:2 >>.

[rgowka1]

Hi -

I am using zlib:compress and uncompress on bitstring.

The expression zlib:uncompress( zlib:compress ( << 255, 3:2 >>  )) =:=
<< 255, 3:2 >> is evaluating to false.

zlib:uncompress( zlib:compress ( << 255, 3:2 >>  )).
<<"ÿ">>

<< << X >> || << X:1 >>  <= <<"ÿ">>  >>.
<<1,1,0,0,0,0,1,1,1,0,1,1,1,1,1,1>>

 << << X >> || << X:1 >>  <= << 255, 3:2 >>  >>.
<<1,1,1,1,1,1,1,1,1,1>>

Is this a bug with the zlib library or  am I missing something basic here?


thanks
