--- Comment #11 from Jack Howarth <howarth at nitro dot med.uc.edu> 2012-11-13 20:13:18 UTC ---
For the simple test case...

int main()
{
int i;
i=5;
}

compiled with 'g++-fsf-4.8 -faddress-sanitizer -O0 -framework CoreFoundation
test.cc -lasan'
using a mach_override.c with...

#define DEBUG_DISASM 1
// #undef DEBUG_DISASM

the errors appear late in the debug output at...

Replacing function at 0x11183d630
First 16 bytes of the function: 48 8d 5 11 4f b 0 53 48 8d 5f e0 48 89 77 90 
To disassemble, save the following function as disas.c and run:
  gcc -c disas.c && gobjdump -d disas.o
The first 16 bytes of the original function will start after four nop
instructions.

void foo() {
  asm volatile("nop;nop;nop;nop;");
  asm volatile(".byte 0x48, 0x8d, 0x5, 0x11, 0x4f, 0xb, 0x0, 0x53;");
  asm volatile(".byte 0x48, 0x8d, 0x5f, 0xe0, 0x48, 0x89, 0x77, 0x90;");
}
