Thank you very much for doing that!

The key line is clearly this:

struct security_ace            contains    696 bytes in   1 blocks (ref
0) 0x7f87f49081f0

That is, one (and only one) security_ace remains on frame, and not on
mem_ctx where it should be.  Indeed, it really should be a child of psd
(so as to move with the rest of the SD).

I'll look over the code again, to see if I can find what would generate
this.
