>Description:
I get an internal error when compiling the libstdc++-v3 library:

../../../../libstdc++-v3/src/complex_io.cc:45:   instantiated from here
../../../../libstdc++-v3/include/bits/std_complex.h:375: Unrecognizable insn:

                (const_int 8 [0x8])) 0)
        (reg:DF 55)) -1 (nil)
    (expr_list:REG_DEAD (reg:DF 55)
        (expr_list:REG_DEAD (reg/f:SI 43)
            (nil))))

>How-To-Repeat:
Compile in the build directory + arm-wrs-vxworks/libstdc++-v3/src:
