Test case 1

---------------
void main() {
    assert(0);
}
---------------

Running this program on 10.7 causes

  Bus error: 10

while the expected output should be something like

  core.exception.AssertError@y(2): Assertion failure
  ----------------
  5   y                                   0x00009265 onAssertError + 65
  6   y                                   0x000126ca _d_assertm + 30
  ...


Test case 2

---------------
void main() {
    throw new Exception("");
}
---------------

Running this program on 10.7 causes

  y(96008) malloc: *** error for object 0x14b060: pointer being freed was not
allocated
  *** set a breakpoint in malloc_error_break to debug
  Abort trap: 6

while the expected output should be something like

  object.Exception@y.d(2): 
  ----------------
  5   y                                   0x00002320 _Dmain + 80
  6   y                                   0x00012dc7 extern (C) int
rt.dmain2.main(int, char**).void runMain() + 23
  ...

I suspect the stack-trace routine has some code depending on having no ASLR, so
I've marked it a druntime problem.
