--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Hello.
Is it possible to reproduce the ICE on x86_64 by adding '-m32' to {C,LD}FLAGS.
I face following SEGFAULT (with -fprofile-generate -lto -m32) in:
gdb --args ./Programs/_freeze_importlib ./Lib/importlib/_bootstrap.py
Python/importlib.h
(gdb) r
Starting program:
/home/marxin/Programming/Python-3.5.0a4/Programs/_freeze_importlib
./Lib/importlib/_bootstrap.py Python/importlib.h
Got object file from memory but can't read symbols: File truncated.
