cyg_mutex_init ( ) - initialize a mutex: Synopsis: void cyg_mutex_init ( cyg_mutex_t *mutex /* mutex to initialize */ ) Description: This initializes a mutex for use. Note that mutexes under eCos cannot be locked multiple times by the same thread.

The pthread_mutex_init() function initializes the specified mutex. If attr is non-NULL, the attributes specified are used to initialize the mutex. If the attribute object is modified later, the mutex's attributes are not affected. If attr is NULL, the mutex is initialized with default attributes, as specified for pthread_mutexattr_init(). Any thread or process interested in the robust lock can call mutex_init() to potentially initialize it, provided that all such callers of mutex_init() specify the same set of attribute flags. In this situation, if mutex_init() is called on a previously initialized robust mutex, mutex_init() will not reinitialize the mutex and will return the error value EBUSY.

Later, ecp_mul_comb calls ecp_drbg_free() which calls mbedtls_ctr_drbg_free() which deletes the mutex, but then ecp_drbg_free() immediately re-creates the mutex using mbedtls_mutex_init(). So when ecp_mul_comb exits there is still a mutex malloc’ed but not free’ed.
