About exceptions: Is try, catch and thow supported?

I would like to use try-catch statements, but it does not seems to work for me. I work with Quartus II 11.0sp1 and nios II (the fpga includes a vic). When I debug what happens in my throw state...

FWIW, I can see that the exception stack unwind fails at the gcc_assert in this function.

static inline void

_Unwind_SetSpColumn (struct _Unwind_Context *context, void *cfa,

_Unwind_SpTmp *tmp_sp)

{

int size = dwarf_reg_size_table[__builtin_dwarf_sp_column ()];

if (size == sizeof(_Unwind_Ptr))

tmp_sp->ptr = (_Unwind_Ptr) cfa;

else

{

gcc_assert (size == sizeof(_Unwind_Word));

tmp_sp->word = (_Unwind_Ptr) cfa;

}

_Unwind_SetGRPtr (context, __builtin_dwarf_sp_column (), tmp_sp);

}
