Ok, I can reproduce this error with both 4.3.2-2 and 4.3.0-2 of TDM's 
gcc port.
I see that r8700:314be237cd5b changed a bunch of code and also 
introcuded the doubly-defined function
octave_sort<std::complex<double> 
>::ascending_compare(std::complex<double> const&, std::complex<double> 
const&)
which ld complains about

hmm, I don't see the bug in the code immediately.

Is this error seen on other platforms too, or is it a mingw-specific 
gcc/ld problem?
