The specific fix is simple: replace the void[] with void*[].
The generic "fix" is just to add a line to
http://www.digitalmars.com/d/garbage.html adding that hiding your only
reference in a void[] results in undefined behavior. I don't think this
should be an inconvenience to any projects?
What do you use for "may contain unaligned pointers"?
Sorry, what do you mean? I don't understand why such a type is needed?
Implementing support for scanning memory ranges for unaligned pointers will
slow down the GC even more.
Because you can have a struct with align(1) that contains pointers. Then
these pointers can be unaligned. Then an array of those structs cast to
a void*[] would contain pointers, but as an optimization, the GC would
consider the pointers in this array aligned because you tell it they are.
