in thread unpack() removing data

On my system (Fedora 17, perl v5.14.3) it strips out hex 0D (CR) in both cases. Handling of line terminators is documented as being system-dependent, though. Without knowing exactly which character being deleted (and the characters before and after it) and what flavor of system you are running on it's hard to guess what the problem might be. You might try this and see if the two dumps are different; if they are you can start looking at sg_logs rather than at your perl script...

sg_logs --page=0x34,1 pd1 -H -r > temp.bin od -x temp.bin | head sg_logs --page=0x34,1 pd1 -H -r | od -x | head

    the system is win7 strawberry perl 5.12.3.0. it does look like the byte being removed is 0x0d consistently. i'll explore that a bit. this is a good lead. thanks!

[holli]: this really really should not be executed as Javascript
erix's head is getting content indisposed
[holli]: maybe try a GET instead?
[moritz]: I must say, when I was very active on perlmonks, I got really used to the markup and all the workflows
[moritz]: and then I didn't post for a while, and then tried to answer a question. It nearly drove me nuts
[moritz]: when you try to quote part of a question, you have to know/guess/reverse -engineer what kind of markup they used
[holli]: see? https://imgur.com/ a/XpF4b
[moritz]: and stuff it into a <blockquote>...</ blockquote>, which is, like, not at all bulky
[moritz]: specially if you're used to markdown
[holli]: there probably is some nodelet hack that lets you use markdown :)
