Very nice. But currently only works with asserts from D code, whereas
most of the ICE's I found on bugzilla come from C code (backend or glue
layer).

I think it should be possible to "hijack" the C assert() by replacing
all instances of #include <assert.h> with something else that redirects
the call to a custom function, perhaps one that calls the D assert
handler.

(Or, failing that, we can use an IOCCC-style hack of re-#define-ing the
assert macro to something else after the fact. Thankfully the C/C++
assert isn't a keyword, so it's easier to hijack. :-P)

There's also util_assert() in backend/util2.c, which can also be
redirected this way.
