I spent a limited amount of debugging on it, but the common problem is that on
i386 (aka 32-bit x86) all programs compiled with -fsanitize=address now die
with:

==11122==AddressSanitizer CHECK failed:
/usr/src/contrib/compiler-rt/lib/asan/asan_poisoning.cc:36

    #6 0x8092785 in clock_gettime (/share/dim/src/misc/hw+0x8092785)

When I put some printfs in there, it showed that the expected address
granularity is 8, but the address to be checked was aligned on 4 bytes:

DBG: addr=0x284429f4, granularity=8

Tracing back the definitions, I found:

#define SHADOW_GRANULARITY (1ULL << SHADOW_SCALE)

then:

#define SHADOW_SCALE kDefaultShadowScale


then:

static const u64 kDefaultShadowScale = 3;

So this seems to be hardcoded.  There is a similar declaration in llvm's
lib/Transforms/Instrumentation/AddressSanitizer.cpp.

I know that it *did* work at some point in the past, but it got broken in recent
history.  I will have to do some archeology to figure out what happened.

Does anybody know whether the shadow granularity was different at some point?

Kostya, does this ring any bells for you?

Ok, some further research showed that I have been conflating two different
issues here.

The first issue is that FreeBSD 12-CURRENT recently received an update to
jemalloc, our default memory allocator, in https://reviews.freebsd.org/rS319971.
For some reason, this causes an alignment problem now when ASan is initializing.
E.g. exactly the same ASan test case works as expected on FreeBSD 10 and 11, but
on 12 it results in:

    ==22338==AddressSanitizer CHECK failed:
/home/dim/llvm-4.0.1/final/llvm.src/projects/compiler-rt/lib/asan/asan_poisoning.cc:36

While this is pretty unfortunate, it is not really a problem with the 5.0.0
release, since it also happens with ASan-instrumented executables compiled by
earlier versions of clang.

The other issue, which I encountered while building 5.0.0 rc1 on FreeBSD 10, is
in compiler-rt itself.  It's apparently being caused by
https://reviews.llvm.org/rL305058 ("Fix ASan internal failure in
AllocateFromLocalPool"), meant to address PR 33206.  Before this commit, on
FreeBSD 10, I got just two ASan-related failures (both of which are pretty old,
I think):

    Failing Tests (5):

        LLVM :: tools/llvm-objdump/X86/macho-literals.test

After r305058, that ballooned to 55 ASan-related failures:
