Greetings!

The segmentation fault you are encountering is likely due to a conflict between how memory is managed by jemalloc and the native components of the Azure Speech SDK. Specifically, the issue arises when the service tries to access memory managed by jemalloc, leading to an ACCERR segmentation fault.

To resolve this issue, follow these steps:

1. Provide a Sample Project: Create and share a basic sample project that replicates the problem. This will help the support team understand your environment and the specific conditions under which the segmentation fault occurs.
2. Review Code and Environment: Ensure that your code and environment setup align with the Azure Speech SDK requirements. Avoid using memory allocators like jemalloc if they are not officially supported.
3. Error Logs and Screenshots: Collect and share detailed error logs and screenshots of the segmentation fault. This information will be crucial for diagnosing the issue.
4. Support team: Reach out to the support team to discuss the issue in real-time. This will help expedite the troubleshooting process.
