(c3bc2787b8beb7aae67fdf2a7f7271a9a4edca7c),
Solaris/SPARC bootstrap began to fail with a SIGBUS in cc1 compiling stage 1
libgcc.

--- Comment #1 from Aldy Hernandez <aldyh at gcc dot gnu.org> ---
Since this happens while building libgcc during stage1, perhaps this can be
reproduced with a cross? Would it be possible to get the preprocessed file
that's failing?
You could try /var/gcc/reghunt/sigbus-range/288807/./gcc/xgcc -save-temps [blah
blah], and attach the libgcc2.i file that gets generated.

What compiler version are you starting with?
It could be that compiler is miscompiling stage 1 here; especially when it
comes to C++ usage is becoming more and more.

I doubt this can be seen in a cross: running the compilation under truss
reveals
the SIGBUS as
2834: Incurred fault #5, FLTACCESS %pc = 0x00723E58
2834: siginfo: SIGBUS BUS_ADRALN addr=0xFFBFC954
2834: Received signal #10, SIGBUS [caught]
2834: siginfo: SIGBUS BUS_ADRALN addr=0xFFBFC954
i.e. an unaligned access. While SPARC is a strict-alignment target, x86 cares
little if any about alignment at all.

Sure, please find _muldi3.i attached.
cc1 invocation is
cc1 -fpreprocessed _muldi3.i -quiet -dumpbase _muldi3.c -dumpbase-ext .c
-mcpu=v9 -g -g -g -O2 -O2 -O2 -Wextra -Wall -Wno-narrowing -Wwrite-strings
-Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition
-version -fbuilding-libgcc -fno-stack-protector -fPIC -fvisibility=hidden -o
_muldi3.s

I see the issue then.
char m_buffer[sizeof (int_range_max)];
Needs _Align to get the alignment correct.

The other way of fixing this is to use an union and I think since we are using
C++11, it might work correctly.
I do think we should prefer the union rather than having it as a char array too

If a union works then indeed that's what we should use.

If Aldy does not fix it by Saturday, I will give the union a try then. I will
also try out the solaris machine on the compile farm if possible.

Great, thanks. Your alignas patch also worked fine btw.

Otherwise, you can just send it my way and I'll give it a whirl.

Sorry, didn't mean for you to pick this up. Thanks for the analysis. I can
take it from here.

I can give the patch a whirl, thanks.
I had Andrew's patch in my tree to avoid the issue. Unfortunately,
Solaris/SPARC bootstrap is broken again due to PR ipa/114985.

I've attached a rebased patch against current mainline. Let me know if it
works on your end, and I'll commit.

I have provided a patch for that PR as well, but the IPA folk need to say if
this is the correct approach.

Thanks for testing. I'll close this PR as fixed in mainline then. FWIW, I
also retested on x86-64 Linux.
