The following is a modified version of the custom allocator example in the docs. The class has to be empty, ie. without any members, for the crash to occur. Still I thought I should report it since it might be a symptom of a deeper problem.

# import std.c.stdlib;
# import std.outofmemory;
# import std.gc;
# import std.stdio;
#
# class Foo
# {
#   new(uint sz)
#     {
#       void* p;
#
#       p = std.c.stdlib.malloc(sz);
#
#       if (!p) throw new OutOfMemoryException();
#
#       addRange(p, p + sz);
#
#       writefln("Allocated %d bytes at ", sz, p);
#
#       return p;
#     }
#
#   delete(void* p)
#     {
#       writefln("Freeing ", p); // This line is never reached
#       if (p)
#       {
#         removeRange(p);
#         std.c.stdlib.free(p);
#       }
#       writefln(p, " is free!");
#     }
# }
#
# void main()
# {
#   Foo f = new Foo;
#   delete f; // The delete command causes the crash
# }

Output:
Allocated 8 bytes at 93072f8
Segmentation fault
