the following 12 ACATS test started failing on x86_64
cxg1001 cxg1002 cxg1003 cxg1005 cxg2002 cxg2006 cxg2008 cxg2009
cxg2018 cxg2019 cxg2020 cxg2021
I see the same thing.

(just before Arnaud commits), the following 12 ACATS test started
failing on x86_64 (but pass on x86):
cxg1001 cxg1002 cxg1003 cxg1005 cxg2002
cxg2006 cxg2008 cxg2009 cxg2018 cxg2019
cxg2020 cxg2021
They all test complex accuracy and fail pretty
badly so that's probably a code generation problem.
