Sorry for taking so long, I opened a PR for spiff, but its not a
regression, see PR6785.
To sum up: all tests (including native) run out of memory, llvm 2.6 had
this problem too, but it didn't miscompare (it was all Out of memory).
Now in 2.7 the JIT crashes when running out of memory.

While that is a bug, I'm not sure if its part of the release criteria.
I tried to make some changes in MallocSlabAllocator to not crash, but
then FoldingSet crashed on OOM.

P.S.: looking at the current 2.7 release blockers I only see PR6696 as
relevant, the others are warnings, experimental code, and a fortran failure.
Is that the case, or are the others release blockers too?

Best regards,
