Source: tbb
Version: 2017~U7-8
Severity: important
Tags: upstream
Justification: fails to build from source (but built successfully in the past)
User: debian-m...@lists.debian.org
Builds of tbb for m68k (admittedly not a release architecture) have
been failing lately:
In file included from ../../src/tbbmalloc/Customize.h:25:0,
from ../../src/tbbmalloc/TypeDefinitions.h:58,
from ../../src/tbbmalloc/tbbmalloc_internal.h:25,
from ../../src/tbbmalloc/backend.cpp:23:

applied on LastFreeBlock, and we put it at the end of region, that is
uintptr_t-aligned, so no unaligned atomic operations are possible.

Could you please take a look? IIRC, on m68k, atomic<int> and the like
are wider than their parameters.
Thanks!
