As those are already on master, and just in case people didn't have time to
test again this bug...

... I tried the scenarios pointed at comment #0 and at comment #1 on haswell.
Although there are still some valgrind warnings, the one pointed by the bug
(use after free, example "Address 0xd3e8ca4 is 884 bytes inside a block of size
1,040 free'd") are gone. 

So probably it is safe to close the bug now. Will let Ilia give the final word.
