Hi,

It only seems to happen on 9.3 (I first noticed it in poudriere)

https://redports.org/buildarchive/20140813152701-50411/

The only difference I could see is that 9.3 has this line in the configure log:

"checking whether cc supports -Wvla... yes"

while 9.2 has:

"checking whether cc supports -Wvla... no"

emmintrin.h fix for gcc 4.2 by dim@
Comment 4 Po-Chuan Hsieh freebsd_committer freebsd_triage 2014-08-13 18:15:18 UTC 
dim@ said:

This is a bug in gcc's emmintrin.h header.  I have committed a fix to
head in r269948, and I will merge it to stable/10 and stable/9 in three
days.  Meanwhile, please apply the attached diff to emmintrin.h in
/usr/include/gcc/4.2 manually.

Comment 6 Matthias Andree freebsd_committer freebsd_triage 2014-08-13 21:03:42 UTC 
Sunpoet, since I'm not sure if we'll have an erratum,
and how fast they propagate to systems, may I propose:

- please use either clang or a newer GCC version on the affected systems (9.3-RELEASE on amd64 for me). That avoids the broken header of gcc 4.2.
Comment 7 vladimir.chukharev 2014-08-14 06:07:03 UTC 
Manual patching the header file as proposed helps me to build the port, thanks. Awaiting for MFC.
Comment 8 Matthias Andree freebsd_committer freebsd_triage 2014-08-15 20:56:56 UTC 
sunpoet, can you see if it helps to copy the *patched* emmintrin.h header in the right WRKSRC directory?

Instead of shipping a patched emmintrin.h, we could:
1) Add CPPFLAGS+=-flax-vector-conversions
2) Add USES=compiler:c11

I would choose the latter. It works on 9.3-RELEASE, 10.0-RELEASE and 11-CURRENT.
Comment 10 Matthias Andree freebsd_committer freebsd_triage 2014-08-16 16:23:22 UTC 
Either is fine for me.
Comment 11 Po-Chuan Hsieh freebsd_committer freebsd_triage 2014-08-17 18:57:48 UTC 
It should be fixed in r365223. Thanks!
