Issue generating bytes

[half-potato]

This is happening on Manjaro, with all of the most recent libraries and GCC.

I am able to workaround this issue by simply correcting the missing 0 and newline.

What are the steps to reproduce this? We have never seen this kind of error on our CI or dev machines.

[half-potato]

I've managed to reproduce this error on two separate machines running Manjaro with gcc (GCC) 14.2.1 20240910. In my experience, it's always GCC. Could be something else though.

@half-potato we don't have this setup to reproduce the issue. Are you able to compile with Clang?

[half-potato]

To reproduce:

# Use an NVIDIA CUDA base image that includes development libraries
FROM nvidia/cuda:12.2.0-devel-ubuntu22.04

# Non-interactive mode for apt-get
ENV DEBIAN_FRONTEND=noninteractive

# Set an environment variable for OptiX installation.
# Adjust this to wherever you've placed OptiX inside the container or mount at runtime:
ENV OPTIX_INSTALL_DIR=/opt/OptiX_7.4

# ------------------------------------------------------
# 1) Install System Dependencies
# ------------------------------------------------------
RUN apt-get update && apt-get install -y --no-install-recommends \
    wget \
    git \
    cmake \
    build-essential \
    libglew-dev \
    libassimp-dev \
    libboost-all-dev \
    libgtk-3-dev \
    libopencv-dev \
    libglfw3-dev \
    libavdevice-dev \
    libavcodec-dev \
    libeigen3-dev \
    libxxf86vm-dev \
    libembree-dev \
    libabsl-dev \
    libcgal-dev \
    libglm-dev \
    && rm -rf /var/lib/apt/lists/*

# ------------------------------------------------------
# 2) Install a Miniconda / Conda environment
#    - We use Miniconda3 as an example here.
# ------------------------------------------------------
RUN wget --quiet https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh && \
    bash Miniconda3-latest-Linux-x86_64.sh -b -p /opt/conda && \
    rm Miniconda3-latest-Linux-x86_64.sh

# Make conda available and create environment
ENV PATH="/opt/conda/bin:${PATH}"
RUN conda update -n base -c defaults conda && \
    conda create -n ever python=3.10 -y && \
    conda clean -ya

# By default, we activate conda env inside container with a script or using ENV:
SHELL ["/bin/bash", "-c"]
RUN echo "conda activate ever" >> ~/.bashrc

# ------------------------------------------------------
# 3) (Optional) Install Slang
#    Replace this section with the correct steps to install or build Slang from source if needed.
# ------------------------------------------------------
RUN git clone --recursive https://github.com/shader-slang/slang.git /opt/slang && \
    cd /opt/slang && \
    # Example: build from source; replace with actual Slang build instructions
    mkdir build && cd build && \
    cmake -DCMAKE_BUILD_TYPE=Release .. && \
    make -j"$(nproc)" && \
    make install

@half-potato: For the ever_training repo, do you need to compile Slang from scratch? Could you pull the pre-built binaries from here (https://github.com/shader-slang/slang/releases) instead? There's usually a release every other week.
