------- Comment #2 from clugdbug yahoo.com.au 2009-04-03 02:28 -------
The first case no longer segfaults -- it stack overflows instead, and the
second case now generates an error.
On DMD1.042, the first case displays:
fog.d(2): Error: alias fog.a recursive alias declaration
Stack overflow
and on DMD2.027, it gets caught in an infinite loop:
fog.d(2): Error: alias fog.a recursive alias declaration
fog.d(2): Error: alias fog.a recursive alias declaration
fog.d(2): Error: alias fog.a recursive alias declaration
fog.d(2): Error: alias fog.a recursive alias declaration
fog.d(2): Error: alias fog.a recursive alias declaration

This is fixed in DMD2.030, but not in DMD1.045.
