Are there any differences between the usart3 and the others ???

No should act in materially the same way. I wouldn't be using printf()'s under interrupt. Perhaps you can use a debugger, or toggle a GPIO/LED? How exactly does it fail? Does the USART3 working in polling mode to actually receive characters? If the processor crashes, how/where does this occur?

Yeah, I got that, so use a debugger and figure out where it's gone, review the .MAP file, listing files and linkage and confirm the vector is pointing at the right routine, and what exactly is going on. Use some breakpoints.
