Huh, the line numbers don't make any sense.
I wonder what
ld warning: atom sorting error for operand::gen_transform(__sFILE*, char
const*, bool, int, char const*, capture_info*, dt_operand**, bool) and
hash_table<id_base, xcallocator, false>::find_with_hash(id_base const*,
unsigned int) in build/genmatch.o
means and if that explains things? Like it ends up calling the wrong
function because of a linker bug? Can you paste the linker command for
linking stage2 build/genmatch and the output when -v -Wl,-v -Wl,-debug is
appended?
As far as I understand ld on ppc-darwin is a GNU ld variant, correct?
I can't find anything in current binutils though. Mike?
