ArrayMath crashes on x86_64 macOS and Linux during HRTF creation

[Ravbug]

System Information Please provide the following information about your system:

• Operating System and version:
  • macOS 14.5 (23F79)
  • Ubuntu 24.04
• Compiler:
  • AppleClang 15.0.0.15000309
  • gcc 13.2.0-23ubuntu4
• CPU architecture: x86_64

Issue Description SteamAudio on x86_64 macOS and Linux compiled to not use Intel IPP crashes during HRTF creation. This issue does not affect arm64 macOS or x86_64 Windows. Configure output:

-- CMAKE_CXX_FLAGS: 
-- Could NOT find IPP (missing: IPP_core_LIBRARY IPP_vm_LIBRARY IPP_s_LIBRARY IPP_INCLUDE_DIR) 
-- Disabling IPP
-- Found PFFFT: PFFFT  
-- Found MySOFA: mysofa-static  
-- Found FlatBuffers: $<TARGET_FILE:flatc> (found version "23.5.26") 
-- Could NOT find ISPC (missing: ISPC_EXECUTABLE) (Required is exact version "1.12")
-- Could NOT find Embree (missing: Embree_sse2_LIBRARY Embree_sse4_LIBRARY Embree_avx_LIBRARY Embree_avx2_LIBRARY Embree_lexers_LIBRARY Embree_math_LIBRARY Embree_simd_LIBRARY Embree_sys_LIBRARY Embree_tasking_LIBRARY Embree_INCLUDE_DIR) (Required is exact version "2.17")
-- Disabling Embree

Steps To Reproduce Steps to reproduce the behavior:

1. Compile SteamAudio for x86_64 macOS or Linux without Intel IPP.
2. Compile and run the included reproducible case
3. See error

If you are able to provide a minimal project or minimal source code that reproduces the issue, include a link to the project/code here.

int main(){
    IPLContext steamAudioContext;
    IPLContextSettings contextSettings{
        .version = STEAMAUDIO_VERSION,
    };
    auto errorCode = iplContextCreate(&contextSettings, &steamAudioContext);

    IPLAudioSettings audioSettings{};
    audioSettings.samplingRate = 44100;
    audioSettings.frameSize = 512;

    IPLHRTFSettings hrtfSettings{
        .type = IPL_HRTFTYPE_DEFAULT,
        .volume = 1.0
    };

    IPLHRTF steamAudioHRTF = nullptr;
    errorCode = iplHRTFCreate(steamAudioContext, &audioSettings, &hrtfSettings, &steamAudioHRTF);  // crashes here

    return 0;
}

I changed some of the SSE intrinsics to their non-aligned versions which enabled the macOS build to get further, so it appears to be an alignment issue.
