Ok, your package indeed produces broken executables. Even simple Hello
world in haskell crashes with bus error. Debugging it gives

Program received signal SIGBUS, Bus error.
0x000000000029e60a in new_gc_thread (n=<error reading variable: Cannot
access memory at address 0x0>, t=<optimized out>) at rts/sm/GC.c:879
879     rts/sm/GC.c: No such file or directory.
(gdb) bt
#0  0x000000000029e60a in new_gc_thread (n=<error reading variable: Cannot
access memory at address 0x0>, t=<optimized out>) at rts/sm/GC.c:879
#1  initGcThreads (from=<optimized out>, to=<optimized out>) at
rts/sm/GC.c:918
#2  0x0000000000297040 in hs_init_ghc (argc=0x7fffffffe544, argv=<optimized
out>, rts_config=...) at rts/RtsStartup.c:242
#3  0x000000000028d15d in hs_main (argc=-7392, argv=0x8,
main_closure=<optimized out>, rts_config=...) at rts/RtsMain.c:57
#4  0x00000000002174a5 in main ()

However, I am unable to reproduce the issue on my side. You could try
building ghc WITH_DEBUG=1 so we can try figure out what's wrong with RTS.

I also noted that OSVERSION of your package is 68, which is even newer that
my recently built 67. Just to rule out base version factor, did you also
have this problem on older version?
