Had you tried "otool -lV"?

Following is the output from 'size -m -l XUL'. For the life of me I
cannot figure out the file offset of the __DATA, __bss and __DATA,
__common sections.
I tried to use heuristics to divine the file offsets but I seem to
end up in the __LINKEDIT segment :-(.
Do I correctly understand that __DATA, __data = __bss + __common?
Thanks, Joel
