DDE27 bug

Can anyone tell me if this bug has been fixed with DDE28. The program below fails to compile with DDE27 with the error:

Norcroft RISC OS ARM C vsn 5.72 [07 Apr 2016]
"RAM::RamDisc0.$.c.Newfile", line 8: Fatal internal error: overwrite 2

Internal inconsistency: either resource shortage or compiler fault. If you
cannot alter your program to avoid this failure, please contact your supplier

__packed struct
{
        unsigned char   action;
        unsigned short  xmin, ymin, xmax, ymax;
} test = 
{
        .action = 24,
        .xmin   = 0,
        .ymin   = 0,
        .xmax   = 1000,
        .ymax   = 1000,
};

int main(void)
{
        return 0;     
}

Can anyone tell me if this bug has been fixed with DDE28

No, same here with DDE28.
