Not sure if related but I also got stung by nested structs in bug 3622.

I don't think so. This bug is filled for GDC, D compiler using GCC backend. And in my situation it is the compiler crash, so i don't have even compiled program.

In your case it is DMD and runtime crash.

My codes (from bug opening, and many more complicated) are working without
problem in DMD).

I cannot reproduce this using gdc 0.25 with gcc-4.1.2 and gcc-4.3.5.

You are right. Works with gcc version 4.3.5 (Debian 1:1.046-4.3.5-2)

Thanks, for update.
