Bug#819429: libstdc++-5-dev: Kodi test crashes in STL on armel and armhf

Package: libstdc++-5-dev
Version: 5.3.1-13
Control: affects -1 kodi

Dear Maintainer,

Kodi fails to build on armel and armhf due to a crashing test:
https://buildd.debian.org/status/fetch.php?pkg=kodi&arch=armhf&ver=16.0%2Bdfsg1-2&stamp=1458793597
...
[----------] 1 test from TestScraperUrl
[ RUN      ] TestScraperUrl.General
[       OK ] TestScraperUrl.General (0 ms)
[----------] 1 test from TestScraperUrl (0 ms total)

[----------] 3 tests from TestSortUtils
[ RUN      ] TestSortUtils.Sort_SortBy
/bin/bash: line 1: 15871 Segmentation fault      /«BUILDDIR»/kodi-16.0+dfsg1/$check_program
Makefile:608: recipe for target 'check' failed
make[1]: *** [check] Error 139
make[1]: Leaving directory '/«BUILDDIR»/kodi-16.0+dfsg1'

I have reproduced the issue on abel.debian.org with Address Sanitizer:

==18199==ABORTING

The test on other architectures does not fail. I'm assigning it to libstdc++-5-dev because it looks like an STL issue in handling the Field constant.

Thanks,
Balint
