opencilk compiler crashing

[gblelloch]

Describe the bug

opencilk clang++ crashes and tells me to: PLEASE submit a bug report to https://github.com/OpenCilk/opencilk-project/issues/

The crash is on compiling a single files of the test suite for parlaylib. Printout below. Based on version of opencilk I cloned today. You can likely reproduce it given instructions below.

Expected behavior

Compile

OpenCilk version

clang version 14.0.6 (https://github.com/OpenCilk/opencilk-project fc90ded\

Built from source as described in: https://www.opencilk.org/doc/users-guide/build-opencilk-from-source/
Also tried downloading and using: https://github.com/OpenCilk/opencilk-project/releases/download/opencilk/v2.0/OpenCilk-2.0.0-x86_64-Linux-Ubuntu-22.04.sh

-OR-

Built from source:

• opencilk-project: branch commit# (or tag)
• cheetah: branch commit# (or tag)
• productivity-tools: branch commit# (or tag)
• infrastructure: branch commit# (or tag) (if applicable)

System information

Ubuntu22

• OS: distribution, version [e.g., Ubuntu 20.04]
• CPU: [e.g., Intel Xeon Platinum 8260]

Steps to reproduce (include relevant output)

TO REPRODUCE:

git clone https://github.com/cmuparlay/parlaylib.git
cd parlaylib
mkdir build
cd build
cmake -DCMAKE_CXX_COMPILER=<pathtoopencilk++> -DPARLAY_OPENCILK=On -DCMAKE_BUILD_TYPE=RELEASE -DPARLAY_TEST=On ..
cd test
make test_delayed_filter_op-nosan

1. [E.g., clone repo X]

2. [E.g., build with parameters XYZ]

   Pass the -v flag to OpenCilk clang/clang++ to show verbose compilation
   commands and output.

3. [E.g., compiler crash output, runtime failure...]

make test_delayed_filter_op-nosan

I have reproduced this and confirmed that it still happens with our latest internal development code.

The bug appears to depend on the C++ or OS headers, because the test program compiles fine on FreeBSD.

[neboat]

Thanks, @gblelloch, for the bug report. We've tracked down the issue and believe we have a fix.

We are currently working on a new release of OpenCilk, and right now the bug fix is based on the new release we are working on. Would you be interested in trying out an early version of the new release?

[gblelloch]

Happy to try out an early version of the new release. Guy

Hey @gblelloch, we have a new version of OpenCilk available for early testing.

The following steps should work to download this new version and build it from source on your system.

$ git clone -b dev/16.x https://github.com/OpenCilk/opencilk-project opencilk
$ git clone -b v2.1-early-test https://github.com/OpenCilk/cheetah opencilk/cheetah
$ git clone -b dev https://github.com/OpenCilk/productivity-tools opencilk/cilktools
$ git clone -b v2.1-early-test https://github.com/OpenCilk/infrastructure
$ infrastructure/tools/build $(pwd)/opencilk $(pwd)/build

After you download and build this early-testing copy of OpenCilk, you should be able to use it via the clang and clang++ binaries and various libraries in $(pwd)/build.

Feel free to forward these instructions to anyone in your group to try out this copy of OpenCilk. Please let us know if you run into any issues or have any questions.

Thanks in advance for your feedback! This version of OpenCilk is not a stable release nor a release candidate, but we are working to prepare a new OpenCilk release based on this version.

[gblelloch]

Sorry it took a while to get to this but Daniel and I were trying it out and the clone of opencilk/cheetah is telling us the branch is not found. Guy

I had a typo in my original instructions, which I tried to correct later. Sorry about that.

The correct branch for cheetah should be v2.1-early-test. In other words, that git command should be:

$ git clone -b v2.1-early-test https://github.com/OpenCilk/cheetah opencilk/cheetah

Let me know whether that resolves the issue for you.

[gblelloch]

We just compiled and ran the parlaylib tests and they all work. When will the fix be released? We need a precompiled version for the ci pipeline for the parlaytests (which pulls from your github release). Thanks, Guy

I'm hoping to release a new version within the next couple of weeks. We're nearly done resolving issues that other early testers found with this new version. We're planning to distribute this revised version to some more testers soon.

Which precompiled binaries are you using, i.e., for which system? If we prepared precompiled binaries for a release candidate of OpenCilk, would that meet your needs?

[gblelloch]

OK, Thanks. I'm ccing to Daniel Anderson who would know for what system. Guy

We have a new version of OpenCilk, based on LLVM 16. We've published Ubuntu 22.04 binaries for that release here: https://github.com/OpenCilk/opencilk-project/releases/download/opencilk%2Fv2.1/opencilk-2.1.0-x86_64-linux-gnu-ubuntu-22.04.tar.gz.

Please let us know if those binaries work for you.

[DanielLiamAnderson]

It works for me in both Release and Debug builds using the current ParlayLib version.
