--- Comment #12 from Thomas Neumann <tneumann at users dot sourceforge.net> --- Created attachment 55037 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55037&action=edit radix sort fix I could reproduce the problem, the radix sort did not behave correctly when we ran out of bits, which can happen on 32bit platforms. The attached patch fixes the problem.
