What is the datatype of the parameter to the proc?

As an explanation - when you use the first form DBD::Sybase assumes that the parameter is of type VARCHAR, which may not handle the NUL bytes very well (although I think it should, really).

If the parameter is supposed to be a binary parameter (VARBINARY, for example), then you should do something like this: 

$sth = $dbh->prepare("exec my_proc ?");
$sth->bind_param(1, $packed, SQL_BINARY);
$sth->execute;

or convert the packed value to a hex string and pass it as a hex string litteral (method #2).
