Crash in mksnapshot while building 4.5.0 on debian wheezy

[SoCalBeachrunner]

• Version: node 4.5.0
• Platform: Debian 7.11
• Subsystem: Wheezy , building node with clang 3.4

node 4.5.0 source fails to complete compilation because clang++ has a Segmentation Fault during the build on Wheezy (building for this same architecture to use on the local machine) while processing the node source file "mark-compact.cc"

Note that the build was configured with the option " --without-intl"
Compiler output and stack trace are attached.

clang had a Segmentation Fault and prompted to send this bug report. During the build of node 4.5.0 on Wheezy (building for this same architecture to use on the local machine) clang++ crashed while processing the node source file "mark-compact.cc"

 The node source was downloaded from the official site as node-v4.5.0-linux-x86.tar.xz 

Package: clang-3.4
Version: 1:3.4-1

root@schnauzerpin:/tmp# uname -a
Linux schnauzerpin 3.2.0-4-686-pae #1 SMP Debian 3.2.81-2 i686 GNU/Linux

Tried again after rebooting the system, no change. Confirming that the system is completely up to date, ran "apt-get update" and "upgrade" prior to starting the build.

Issue is 100% reproducible, build fails with same messages each time it's attempted.

The trace at failure point:

Sounds like a duplicate of #8323 to me. That was fixed by #8343 which is marked dont-land-on-v4.x… @ofrobots ?

[ofrobots]

@SoCalBeachrunner Are you sure you have the correct source tarball? The source in v4.5.0 doesn't match the ICE backtrace you posted.

1. ../deps/v8/src/heap/mark-compact.cc:3502:65: current parser token '}'
2. ../deps/v8/src/heap/mark-compact.cc:32:1: parsing namespace 'v8'

It does match the source code for v6.5.0 however, which is expected to hit this ICE with clang-3.4-1.

[SoCalBeachrunner]

Agreed. #8323 didn't turn up in my search. Have read both items and code changes now. Thanks for fast reply. I"ve updated code and restarted my build. It takes a while...

[SoCalBeachrunner]

You know your code best and must be correct. I made a couple download attempts plus re-started all this 3x in the middle of night, first with the tar file then curl piped into the directory, just trying to get node building on the box. I thought this time it was back to the 4.5.0 tar but apparently it's the 6.5.0 from using curl of "latest" at about 2 AM PST. The builds run for hours before failing, long night.

[SoCalBeachrunner]

Perhaps admin wants to correct this post title & version. I appreciate your great work maintaining this project & will confirm build outcome when available. BTW this began because the version 4 binary download wouldn't run on this box. node returned "Illegal instruction" hence decided to see if building locally might work. Really aiming just for v4 node to match the AWS environment, may update the OS over the weekend.

[SoCalBeachrunner]

Just confirming details and that the outcome after a clean start concluded with "Illegal instruction" late in the build after applying "deps: workaround clang-3.4 ICE". If this is as expected I'll close this issue.

[ofrobots]

@SoCalBeachrunner what is the exact CPU you are trying to build this on? e.g. can you provide the output of grep "model name" /proc/cpuinfo. I suspect you are using an older x86-32 processor and the compiler is generating an instructions that your CPU doesn't support.

Do you still see the crash when you configure with --without-snapshot?

[ofrobots]

I just noticed this higher up:

BTW this began because the version 4 binary download wouldn't run on this box.

Based on that, I don't think --without-snapshot would help. The compiler is probably defaulting to an instruction set that your CPU doesn't support. Depending on what precise CPU you have there may be a -march option that avoids this problem. (Assuming that the JIT compiler in V8 has a mode that also supports your CPU).

[SoCalBeachrunner]

model name : Pentium II (Klamath), an old CPU, probably the root cause.
Up to now everything in each distro has built and run without problems. I'm happy to pursue this to conclusion if you have a suggestion or pointer for best arch option(s) to test, will give it a try if it benefits the nodejs or v8 projects in terms of limited CPUs. If you don't want to spend time on what might be an edge case just say the word and we can close this. I'll find a newer box and run Jessie.

[bnoordhuis]

The machine code that V8 emits has a hard dependency on SSE so that rules out the Pentium II. There is a x87 backend but node.js doesn't support it and it's untested. You could hack configure and see if it works for you, grep for valid_arch.

[SoCalBeachrunner]

Hacked to support: ./configure --without-intl --dest-cpu=x87 --prefix=~/local
make install succeeds but node still returns "Illegal instruction"
Thanks, all, for your fast and informed responses. We can put this to rest now.
