Please consider the following program:
-------- main.d --------------
float fun(cfloat z)
{
return z.re;
}
void main()
{
cfloat[1] A;
float[1] B;
int i = 0;
double C = fun(A[i] * B[i]);
}
--------------------------------
Build it with DMD D Compiler v2.079.0 in 64-bit
$ rdmd -m32 main.d
(Builds and run without problem)
$ rdmd -m64 main.d
Internal error: dmd\backend\cgcod.c 607

ICE is always a critical bug.

the ice happens in alignsection, I'll see what else I can come up with.

This is not an ICE by the way, it compiles. The segfault is when the executable is ran.
