g++: internal compiler error: Segmentation fault (program cc1plus) - where do I start?

Question

I am porting code that compiled on Ubuntu 14.04 to 16.04. I have cloned my git repo, installed dependencies and tried the usual make command, soon I hit a g++: internal compiler error: Segmentation fault (program cc1plus) ... yet I am not sure where to start to diagnose and resolve this issue.

I will share as much as I can, see if someone can guide me through a resolution.

Ubuntu

$ lsb_release -a 
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:    16.04
Codename:   xenial

g++

$ g++ --version
g++ (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609

python

$ python --version
Python 2.7.12

Some environment variables

PYTHON       /usr/bin/python2.7
ARCH         x86_64
OS           Linux

BINDIR       build.x86_64-linux2
ODIR         build.x86_64-linux2-gcc
STATICLIBDIR build-static.x86_64-linux2

Error

The make command leads to

+++ Compile mycore/boost_json.cc to build.x86_64-linux2-gcc
g++: internal compiler error: Segmentation fault (program cc1plus)   <===
Please submit a full bug report,

See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.

Makefile:152: recipe for target 'make.stage1c' failed
make: *** [make.stage1c] Error 2

The error message seems to be pointing at a g++ compiler error (?)

makelib2.inc:48

$(ODIR)/%.o : %.c
        @mkdir -p $(dir $@)
        @echo "+++ Compile $< to $(ODIR)"
        @$(CC) -MMD -MP -MF $(@:.o=.d) -c -I$(ODIR) $(CFLAGS) $(CFLAGS_$*) -o $@ $<

I realize that this is going to be very difficult to craft a proper question that would lead to getting proper help. So please bear with me and feel free to suggest adding anything that may help. Unfortunately, I can't share the code.

Update

Going to try upgrade g++ to a more recent version. Following this thread

HERE how to install g++ 7 on Ubuntu

HERE how to install gcc 6 on Ubuntu

We probably need to see what command-line was generated for @$(CC) -MMD -MP -MF $(@:.o=.d) -c -I$(ODIR) $(CFLAGS) $(CFLAGS_$*) -o $@ $< when compiling the boost_json.o target. – Sarcenet

Like the error message say, you should file a bug report to gcc (if there is not already one for the same bug). Internal compiler error are always bug in the compiler. – Martell

Report it here gcc.gnu.org/bugzilla 5.x is old though, you may want to install a newer version. – Randers

ha! I figured I was working with latest. on my Ubuntu 14.04 I was working with g++ (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4. – Vaticide

@n.m. do you know the right way to upgrade g++ to its latest version. I think your suggestion may resolve my issue, please feel free to add it as answer. – Vaticide

Try to find a GCC version 6 at least. Since GCC 7 has been recently released. – Breeding

Answer 1

How I resolved my g++ segmentation fault issue

Inspired by this thread

I executed the following on my Ubuntu 16.04

   sudo apt-get install build-essential software-properties-common -y
   sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y 
   sudo apt-get update
   sudo apt-get install gcc-snapshot -y 

After what g++ was incremented from 5.4.0 to 5.4.1 which resolve the segmentation fault issue

$ g++ --version
g++ (Ubuntu 5.4.1-2ubuntu1~16.04) 5.4.1 20160904

I know it's old, but this fixed the issue for me too. Cheers – Kufic

This answer really saved my day – Turaco

THANK YOU SO MUCH FOR THIS. I had an issue in WSL and I was trying to solve it for a while now with no hope, this fixed it for me! To be exact my issue was this: # github.com/mattn/go-sqlite3 during RTL pass: reload sqlite3-binding.c: In function ‘sqlite3Parser’: sqlite3-binding.c:173143:1: internal compiler error: Segmentation fault 173143 | } | ^ 0xd7a791 internal_error(char const*, ...) ???:0 0x11754f6 lra_constraints(bool) ???:0 0x116c72f lra(_IO_FILE*) ???:0 – Tyche

Answer 2

Simply do as you were instructed:

Please submit a full bug report, with preprocessed source if appropriate.

Pneumato

right, I guess that's one thing, although that doesn't resolve my issue. What might resolve is installing (as suggested in the comments) a more recent version of the g++ on Ubuntu 16.04 if that's supported, because this issue may have been resolved already right? – Vaticide

The people who receive your bug report will be best placed to help you triage it and find a workaround. – Pneumato

Answer 3

If you can't solve your problem using above methods, you can have a try to check if you are running out of disk space using below command. This is the workaround of my problem.

df -h
sudo du -h --max-depth=1
