12948,Unexpected snprintf result is on Android ARM,Lev Sch <zorechfan@…>,olli,"I observe strange results from snprintf function: the function returns ""0x34567890E20242C1"" instead 0x0BCDEF1234567890. It ""shifts"" number!

notes:
1. it is reproduced on boost_1_63_0 & boost_1_64_0_b2.
2. is not reproduced on boost_1_62_0
3. device: Android Marshmallow arm64-v8a
4. android-ndk-r14-windows-x86_64 is used (by Android Studio). ""windows-x86_64"" is architecture an application is build on
5. test executable architecture is armeabi-v7a

Used compiler flags:

{{{
    -fexceptions
    -std=c++14
    -DBOOST_NO_TYPEID
    -DBOOST_EXECUTION_CONTEXT=1
    -fno-rtti
}}}
