The following code crashes DMD v2.053 with "Internal error: ../ztc/cgcs.c 363": class foo { int opApply(int delegate(ref int) dg) const { return 0; } foo bar() out(result) { foreach (x ; result) foreach (y ; result) assert(x); } body { return this; } } I haven't been able to simplify the code any further and still reproduce the crash. Removing the second foreach makes it compile, as does replacing "assert(x)" with anything not referring to "x".

Also crashes on 2.059 Win32.
