Comment(by gwright):
This does appear to be a linker bug. I can reproduce it just by running
`ghc-stage2 --interactive`. The incorrectly resolved symbol is
`_stg_bh_upd_frame_info`. This address is pushed on the stack in
`_base_GHCziIOziHandleziFD_stdin_info` (referenced in
`initInterpBuffering`). `_stg_bh_upd_frame_info` is resolved as zero, and
when the null pointer on the stack is dereferenced the crash occurs. In
the simple case of just trying to start `ghc-stage2` interactively, it
happens when `threadPaused` scans the stack.
I'll try `+RTS -Dl` and report what I find.
