Re: Marshal Problem

Robert Evans

Hi Eric,

The Mac OS X version, which works is 1.8.4 (2005-12-24). The windows
version is ruby 1.8.4 (2005-12-24) [i386-mswin32].

The same classes are used to dump and load, from the same irb session
even.

Can you show us how to reproduce the problem?

Hi,

The objects involved were fairly complex, so I will try to create a
simpler case that exhibits the problem.

Hi,

Following up. I finally got back to this issue, and now everything
works fine.
I believe the problem may have had to do with reading and writing the
files that contained the marshalled objects without using the binary
flag.

Thanks for your help,
Bob
