The gc throws invalid memory errors if I use Arrays from std.container.
Those arrays are for RAII-style deterministic memory release, they shouldn't be freely mixed with GC-allocated things. What happens here is while initializing Array sees it got some GC-ed value type (strings), so it tells GC to look after those strings. When your program ends runtime does a GC cycle, finds your Test object, calls its destructor that calls Array destructor that tries to tell GC not to look at its data anymore. But during a GC cycle it's currently illegal to call such GC methods, so it throws an error. Moral of this story: try not to store "managed" (collected by GC) types in Array and/or try not to have Arrays inside "managed" objects. If Test was a struct instead of a class, it would work fine.
