While trying to use the --render command of the Vital CLI on macOS, I got a segfault.

crashreport.txt

ChatGPT's advice based on the crash report:

The crash report indicates that the application Vital crashed due to a segmentation fault (SIGSEGV), which is a type of crash where a program attempts to access a restricted area of memory.

Here are the key points from the crash report:

- **Process**: Vital (audio.vital.synth)
- **Version**: 1.5.5
- **Crashed Thread**: 0 JUCE Message Thread (main thread)
- **Exception Type**: EXC_BAD_ACCESS (SIGSEGV)
- **Exception Codes**: KERN_INVALID_ADDRESS at 0x0000000000000018

The crash occurred in thread 0, which is the main thread of the application. The function call stack indicates that the crash happened during a call to `juce::AudioFormatWriter::writeFromFloatArrays`, which is a function from the JUCE framework used to write audio data. It appears that the application attempted to access memory at address `0x18`, which was not a valid address, leading to the segmentation fault.

It seems this segfault (or something similar to it) has existed since at least March 2021:
