Example below. This seems to be related to DWARF error: section .debug_info is larger than its filesize!

addr2line -e fdbserver.debug -p -C -f -i 0x7fb015e2e630 0x273e056 0x19fc2d8 0x1b0ffb2 0x2747515 0x2746113 0x19fc2d8 0x20626c6 0x32bc46a 0x329ec2d 0x1d6c64f 0x4d92b6e 0x4d92443 0x19fc2d8 0x4e82971 0x4e8248a 0x2fe949c 0x7fb015a73555

We've started using llvm-addr2line to get around this problem. You could also try newer versions of addr2line. I think they were working on some fixes to these problems, though I'm not sure if they are released yet.

Thanks for the tip! llvm-addr2line works fine.
