After digging into this I have found that this line:
movptr(Address(rbp, frame::interpreter_frame_last_sp_offset * wordSize),
(int32_t)NULL_WORD);
from hotspot/src/cpu/x86/vm/interp_masm_x86_32.hpp is causing the problem.
It seems that this version of movptr is for 64 bit architectures. Based on
the comment in hotspot/src/cpu/x86/vm/assembler_x86.hpp
#ifdef _LP64
// Generally the next two are only used for moving NULL
// Although there are situations in initializing the mark word where
// they could be used. They are dangerous.
// They only exist on LP64 so that int32_t and intptr_t are not the same
// and we have ambiguous declarations.
void movptr(Address dst, int32_t imm32);
void movptr(Register dst, int32_t imm32);
#endif // _LP64
Previous version of void empty_expression_stack() used movl instead of
movptr.
I guess _LP64 needs to be defined for Apple/OS X or the guard needs to
include __APPLE__ .
