LDC does a pretty good job with dynamic arrays (including char[] as strings):

Program received signal SIGSEGV, Segmentation fault.
0x08049718 in _Dmain (args=...) at ./bug.d:13
13        *(args.ptr + 1_000_000) = "boom";
(gdb) print i
$1 = {5, 15}
(gdb) print args
$2 = {"./bug", "1", "2", "3"}

Associative arrays seems to be not very well handled by any current compiler...
