---------------------------+------------------------------------------------
HMrmr (github.com/nlhepler/HMrmr) successfully compiles with: {{{ ghc
-fforce-recomp -O -fllvm HMrmr.hs }}}, but when running the HMrmr binary
it segfaults: 11. A gdb trace yields:
{{{
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: 13 at address: 0x0000000000000000
0x00007fff8e6806cd in misaligned_stack_error_entering_dyld_stub_binder ()
(gdb) bt

#2 0x0000000100300440 in pvars ()
Previous frame inner to this frame (gdb could not unwind past this frame)
}}}
The same code compiles and runs fine without -fllvm.
