--- Comment #1 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
The instrumented compiler is obviously miscompiled.
trippels@gcc2-power8 libgcc % cat unwind-dw2.i
void _Unwind_Backtrace() { __builtin_unwind_init(); }
trippels@gcc2-power8 libgcc % /home/trippels/gcc_build_dir_/./gcc/xgcc
-B/home/trippels/gcc_build_dir_/./gcc/
-B/usr/local/powerpc64le-unknown-linux-gnu/bin/
-B/usr/local/powerpc64le-unknown-linux-gnu/lib/ -c -g -O2 unwind-dw2.i
unwind-dw2.i: In function ‘_Unwind_Backtrace’:
unwind-dw2.i:1:1: internal compiler error: in dwarf2out_frame_debug_expr, at
dwarf2cfi.c:1901
