No, but...

...after strcpy() is called, you've lost the pointer that testA
returned, meaning that you no longer have the ability to free that
memory. You want something like

char *tmp=testA();
strcpy( acMsg, tmp ); /* assuming malloc() succeeded - you should check */
free( tmp );

Think about this in relation to infobahn's article :)
