For sure.

#define CONFIGURE_INIT_TASK_ATTRIBUTES RTEMS_LOCAL | RTEMS_FLOATING_POINT

As I said, with 4.6.1, 4.6.2 and 4.6.4 the application worked fine.
After the SPARC update in 4.6.5 it just failed at the initialisation
task (which uses fpu). Removing the -msoft-float from 4.6.6 solved the
problem.

Yesterday I looked at the patch for the whole afternoon and I did not
see anything else that could affect, but I am not an expert in RTEMS
internals, so probably I am missing something.
