--- Comment #3 from Prathamesh <bilbotheelffriend at gmail dot com> ---
It appears the issue is still present on trunk for arm-none-linux-gnueabihf.
Compiling the above code gives following ICE:
(arm-none-linux-gnueabihf-gcc -O -fdata-sections):
fo.c:2:1: internal compiler error: in get_variable_section, at varasm.c:1151
