Bug ID: 58251
Summary: -flto causes ICE lto1: internal compiler error: in
splice_child_die, at dwarf2out.c:4706
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: jpakkane at gmail dot com
With Gcc 4.8.1 on Ubuntu Saucy x86-64 I can reliably trigger an ICE. As the
issue happens during link, I can't reduce it to a single file test case. The
steps to reproduce are these:
bzr branch lp:libcolumbus
cd libcolumbus
mkdir build
cd build
CXXFLAGS=-flto cmake -DCMAKE_BUILD_TYPE=relwithdebinfo ..
make
The output is this:
Linking CXX shared library columbus.cpython-33m.so
lto1: internal compiler error: in splice_child_die, at dwarf2out.c:4706
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.8/README.Bugs> for instructions.

You need CMake, libicu-dev, python3-dev and libboost-python-dev to compile the
library. The version of libboost-python in Ubuntu Saucy is 1.53.
