| In case anyone else is interested I just learned that this is a known bug in lldb which was fixed recently, but evidently the fix has not yet made its way into Apple’s build. I got the following info from Enrico Granata on StackOverflow (see: http://stackoverflow.com/a/33114721/253056):

I cant seem to get lldb’s “memory find” command to work with the -e option.
I've found that the -s option can be made to work, e.g. like this: (lldb) me fi -s "f" -- ptr ptr+8192*256
Your data was found at location: 0x11033e20c
0x11033e20c: 66 bb 58 07 d0 b7 32 7d ff 7f 00 00 66 5b e7 82 f.X...2}....f[..
But it looks like the -e option (which is what I need in this instance) is broken, e.g.:
(lldb) me fi -e 255 -- ptr ptr+8191*256
error: _expression_ evaluation failed. pass a string instead?
Trying to coax the -s option into accepting an escaped hex or decimal value doesn't seem to work either, unfortunately: (lldb) me fi -s "\xff" -- ptr ptr+8191*256 Your data was not found within the range.
(lldb) me fi -s "\255" -- ptr ptr+8191*256 Your data was not found within the range.
Am I missing something in the way I’m trying to use the -e option ?
