Is there any change on interrupt catch between RTEMS 4.9.4 and 4.10.0?

Hi all,
I've recompiled and run two simple applications, thet use ISRs to manage a console/terminal interface.
The BSP is SPARC/SIS. Both applications run successfully on RTEMS 4.9.4, but not on 4.10.0. They simply stop running just after 'rtems_interrupt_catch' is called for the UART A. In fact, it seems that they stop on the first 'printf' after the interrupt catch.
Does anyone have noticed this behavior? Has something changed on interrupt catch between 4.9.4 and 4.10.0? Could be something new on gcc's printf for the SPARC architecture?
Thanks in advance and best regards,
Filipe Cividanes.
