The MicroBlaze processor C and math libraries distributed with Vivado are not built to be used in a multi-threaded environment. Common C library functions such as printf(), scanf(), malloc(), and free() are not thread-safe and will cause unrecoverable errors in the system at run-time. Use appropriate mutual exclusion mechanisms when using the Vivado libraries in a multi-threaded environment.
