           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal

C++ source code

The attached C++ code, when compiled with gcc trunk,
does this:

dsp/v4f_FIR.h:164:50: internal compiler error: in decompose, at wide-int.h:932
0x5cabdb wi::int_traits<generic_wide_int<wide_int_ref_storage<false, false> >
>:
:decompose(long*, unsigned int, generic_wide_int<wide_int_ref_storage<false,
fal
se> > const&)

The bug seems to exist between revisions 256420 and 256556.

I'll have a go at reducing the code.
