Comment:

 I'm seeing something very similar with git head (b8392ae76a6d39) cross
 compiling from a Debian amd64-linux to arm-linux-gnueabihf (beaglebone-
 black running Debian). My test program is:

 {{{
 main :: IO ()
 main = putStrLn "Hello"
 }}}

 and when I copy the compiled binary to the beaglebone and run it, it
 segfaults almost immediately. The GDB backtrace looks like this:

 {{{
 Program received signal SIGSEGV, Segmentation fault.
 0x0021b8dc in stg_init_finish$def ()
 (gdb) bt
 #0  0x0021b8dc in stg_init_finish$def ()
 #1  0x00217116 in threadPaused ()
 #2  0x00000000 in ?? ()
 }}}
