Have you tried building OTP for i386?

IIRC x86_32 has no alignment restrictions meaning SIGBUS should not ever be generated on the architecture. But I read somewhere recently that SSE2 instructions and x86_64 do have alignment restrictions, hence the i386 suggestion above.

Could something be sending SIGBUS to beam?

Are you mixing 64-bit and 32-bit components?
