[Elftoolchain-developers] elf_update() returns error "Invalid data buffer descriptor" on FreeBSD 10.3

[Sam H. <sam...@gm...>]

First time on list,

Failure here: https://github.com/shabiel/fis-gtm/blob/freebsd/sr_x86_64/obj_filesp.c#L322

I added a line after it:
                FPRINTF(stderr, elf_errmsg(elf_errno()));

And this line says: Invalid data buffer descriptor.

Ports tree libelf doesn't have this problem.

root@:~/repos/fis-gtm # uname -a
FreeBSD  10.3-RELEASE FreeBSD 10.3-RELEASE #0 r297264: Fri Mar 25
02:10:02 UTC 2016
ro...@re...:/usr/obj/usr/src/sys/GENERIC  amd64

I don't have any idea on how to find out what version number is the
libelf library on FreeBSD.

Any ideas on how I would troubleshoot this?
