error.
Zero-length types can legitimately arise from declarations
like 'struct {}'. GDB may also create them when it finds
bogus debugging information; for example, in GCC 2.95.4 and
binutils 2.11.93.0.2, the STABS BINCL->EXCL compression
process can create bad type numbers. GDB reads these as
TYPE_CODE_UNDEF types, with zero length. (That bug is
actually the only known way to get a zero-length value
allocated to a register --- which is what it takes to make it
here.)

We'll just attribute the value to the original register. */
