Comment 6 for bug 1556257

I use arm-none-eabi-gcc 5-2015-q4-major
unpacked into /opt/
I have instaled libc6-i386 because arm-none-eabi-gcc 5-2015-q4-major
which I get from here is for i386 while my debian and ubuntu are x64.

dpkg-query -S /opt/gcc-arm-none-eabi/bin/arm-none-eabi-gcc | cut -d ":" -f 1
dpkg-query: no path found matching pattern /opt/gcc-arm-none-eabi/bin/arm-none-eabi-gcc
(because it is not installed via apt system)

>   I have installed 5-2015-q4-major on both ubuntu 14.04 and debian jessie.
>   Both systems are 64 bit with i386 support.
>   On ubuntu I can compile c++ file which uses std::list into binary that runs on stm32f103c8t6 as expected.
>   If I compile exactly the same project on debian jessie, the binary hangs in WWDG_IRQHandler just inside std::list object initialization.
