Thank you for the suggestion Peter. I have tried each of these individually and both in combination, with no change in behavior. :-( If I build without -D_FILE_OFFSET_BITS=64 then my i686-compat code will not run on servers with >2TB disk volumes.
I think this may be an error in the glibc code or build. Any tips appreciated.

The solution is to add "-D_FILE_OFFSET_BITS=64" and this has fixed the issue on glibc and all our other i686 RPM builds.
However, with the latest update glibc-2.12-1.192.el6.src.rpm we find

the above flag will cause the following error:

Has anyone else hit this issue? Any tips appreciated.
Have you tried adding also -D_LARGE_SOURCE or -D_LARGEFILE64_SOURCE ? I remember in the past you had to define both _FILE_OFFSET_BITS=64" and _LARGEFILE64_SOURCE for full 64 bit support for 32-bit programs. I mention _LARGE_SOURCE because it may be relevant here: `-- Macro: _LARGEFILE_SOURCE If this macro is defined some extra functions are available which rectify a few shortcomings in all previous standards. Specifically, the functions 'fseeko' and 'ftello' are available. Without these functions the difference between the ISO C interface ('fseek', 'ftell') and the low-level POSIX interface ('lseek') would lead to problems.
This macro was introduced as part of the Large File Support extension (LFS).'which may be relevant to the ftello error you get.
