            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.
lto-wrapper: /usr/bin/c++ returned 1 exit status
/usr/bin/ld: lto-wrapper failed
collect2: error: ld returned 1 exit status

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.

I can reproduce this with Gentoo gcc-4.8.2 and new KDE's kig package 4.11.4.

How to debug this please?

--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Can you try a GCC 4.9 prerelease?  The usual workaround is to disable debuginfo
generation.

And yes, reducing the testcase to a few input files is necessary - you
can bisect the linker inputs by adding -r -nostdlibs (performing a partial
link).

I've tested this on my Gentoo box and cannot reproduce the issue
on trunk or gcc-4.8 branch. 
So it is most likely already fixed.

I retried this with Gcc 4.8.2 on trusty and no longer get the crash. I have not
tried to reproduce David Kredba's issue so that might still remain.

removed and other object files present on link command it did this:

Good, if you now remove the -Wl,--no-undefined switch you should be able
to remove all shared library inputs as well (fingers crossing).

For the remaining object file inputs (AFAIK only python_scripter.o?) please
attach preprocessed source from the compile-stage.  The bug should then
be reproducible by exchanging python_scripter.o for python_scripter.ii
on the command-line and thus make the bug reproducible with just that
file.

Thanks,
Richard.

And what if you enable randomization?

> Have any attempt for saner tsan shadow memory mapping be done in the last year?

No, there were no such attempts.
But, yes, it would be nice if tsan supports no-ASRL/no-PIE/COMPAT mappings.

You can now further reduce the single testfile by following the 
"Simple ICE reduction" section in the document I've linked to above.

First try to minimize the gcc command line options that you use.
Then write a simple test script, e.g.:

 $ cat chech.sh
/usr/bin/x86_64-pc-linux-gnu-g++ -O2 -ggdb -flto -r -nostdlib -Wfatal-errors
test.ii -o /dev/null  2>&1  | grep 'internal compiler error: in
splice_child_die'
  if ! test $? = 0; then
    exit 1
  fi

and run delta, multidelta or Creduce with it.

Boost testcases are always fun ;-)
For testcase this huge I recommend Creduce, because it runs in
parallel by default.

Confirmed with 4.7.3 and 4.8.2.  Seems to work on the trunk, worked with 4.6.4.

Now it would be interesting to bisect what fixed this on the trunk ...

It was fixed by r200151.

Thank you!

Looks like they are not overweighting it at the Creduce web site, it is way
better then delta. Delta for me ended already 10 times with message that:
"Could not increase granularity; we are done." And after each new start it
removes a few more lines. But I am still at 2052 lines :-).



(I opened a case at Gentoo Bugzilla kindly asking maintainer for bumping to to
the latest stable Creduce.)

Bah .... this means "don't hold your breath for a fix".  I wonder whether
it makes sense to try backporting "4.9 LTO" to 4.8 ... (too much fallout in
the end I guess).
