System Information
Operating system: macOS-13.4.1-arm64-arm-64bit 64 Bits
Graphics card: Metal API Apple M2 Pro 1.2

Blender Version
Broken: version: 3.6.0, branch: blender-v3.6-release, commit date: 2023-06-27 08:08, hash: c7fc78b81ecb
Worked: (newest version of Blender that worked as expected)

Short description of error
Blender crashes when the curve resampling node length is 0

blender::length_parameterize::sample_at_length(blender::Span<float>, float, int&, float&, blender::length_parameterize::SampleSegmentHint*)
blender::length_parameterize::sample_uniform(blender::Span<float>, bool, blender::MutableSpan<int>, blender::MutableSpan<float>)::$_0::operator()(blender::IndexRange) const
void blender::threading::parallel_for<blender::length_parameterize::sample_uniform(blender::Span<float>, bool, blender::MutableSpan<int>, blender::MutableSpan<float>)::$_0>(blender::IndexRange, long long, blender::length_parameterize::sample_uniform(blender::Span<float>, bool, blender::MutableSpan<int>, blender::MutableSpan<float>)::$_0 const&)
blender::length_parameterize::sample_uniform(blender::Span<float>, bool, blender::MutableSpan<int>, blender::MutableSpan<float>)
blender::geometry::resample_to_uniform(blender::bke::CurvesGeometry const&, blender::fn::Field<bool> const&, blender::fn::Field<int> const&, blender::geometry::ResampleCurvesOutputAttributeIDs const&)::$_3::operator()(blender::OffsetSpan<long long, short>) const

Exact steps for others to reproduce the error
Make sure you use a Release build.

Open attached .blend file
Set the Length value of the "Resample Curve" node to 0.0 (or connect the X output of the "Separate XYZ" node to the Length input of the "Resample Curve" node)

This is an irregular operation, but I hope it is not a crash but a warning.
There is also a possibility that if the length is close to zero, it will cause the computer to have 100% CPU.

Hi, thanks for the report. Unable to confirm the crash on Windows (4.0, 3.6 build)
Please share crash logs: https://docs.blender.org/manual/en/dev/troubleshooting/crash.html#macos
Also also verify the crash in recent 3.6.2/4.0 build: https://builder.blender.org/download/daily/
