>Originator:     Gabor Pali
>Release:        FreeBSD/i386 9.2-RELEASE
>Organization:
The FreeBSD Project
>Environment:
Both i386 and amd64, starting from 9.0-RELEASE.
>Description:
GHCi cannot handle ELF symbols with relocation types 15 (i386) and 22 (amd64) (such as ThreadRuneLocale, coming from libc) when dynamically loading object files.

>How-To-Repeat:
This can be reproduced by the issuing the following commands:

# pkg install hs-hs-bibutils
..
$ ghci
Prelude> :m Text.Bibutils
Prelude> bibl_init
Loading package syb-0.4.0 ... linking ... done.
Loading package hs-bibutils-5.0 ... linking ... <interactive>: /usr/local/lib/cabal/ghc-7.6.3/hs-bibutils-5.0/HShs-bibutils-5.0.o: unhandled ELF relocation(Rel) type 15
ghc: unable to load package `hs-bibutils-5.0'
Prelude>

>Fix:
The source file rts/Linker.c, function do_Elf_Rela_relocations() is missing the case branches for types 15 (R_386_TLS_IE) and 22 (R_X86_64_GOTTPOFF).  They shall be implemented for FreeBSD.
