[  331s] !!    ERROR: ureldatefmt_format() for locale fr, decPlaces -1, width 0, capContext 257, offset -0.70, unit 4;

Ok so that looks like someone at ICU forgot to update the testcase, because the plural is indeed the right form.

I'm glad that it's so simply fixable.

Then again, why would this only show up with gcc7…⸘

And why i586 only?!

Great question, looking at the stuff which was changes in GCC 7:
https://gcc.gnu.org/gcc-7/changes.html

Maybe it can be related to -fprintf-return-value.

Then, can you try rebuilding icu with -fno-printf-return-value ?

Hm, the test looks fine, because 'jours' is plural and it should not be used for values <= 1. However -fprintf-return-value is not responsible for that.

Adding -m32 to x86_64 target also triggers the issue.
If I could build the package on my host (w/o OBS), then I can bisect that.

I see:
make[1]: Entering directory '/home/marxin/Programming/osc/openSUSE:Factory:Staging:C/icu/icu/source/test'
Makefile:130: *** target pattern contains no '%'.  Stop.
make[1]: Leaving directory '/home/marxin/Programming/osc/openSUSE:Factory:Staging:C/icu/icu/source/test'
make: *** [Makefile:143: all-recursive] Error 2

Can you please help me?

Ok, can be reproduced on trunk. I should be able to bisect that!

Ok, so it can be reproduced with GCC 6.3.1 and -m32 -O2 on x86_64-linux-gnu. I guess it will need a maintainer to debug that issue.

Sorry for noise, it's really in between GCC 6 and 7 the regression.

Then we should asisgn the bug to the gcc maintainer - not the icu maintainer

=> rguenther

Not a gcc bug but icu running into excess precision issues of x87 math.

SR#495573

please somebody accept and forward.

Should using a cast to (double) work too? http://stackoverflow.com/a/503523
Then I'd prefer that over volatile, I think.

I don't think this will work.  The variables and values are already double,
the issue is only in the FPU keeping excess precision around.

Fixed.
