--- Comment #1 from Gary Funck <gary at intrepid dot com> 2012-07-31 16:12:18 UTC --- We have determined that we can bypass the failure with the following configure switches: --with-long-double-128 --with-cpu-32=power4 --with-tune-32=power6 --with-cpu-64=power4 --with-tune-64=power6 This binutils email thread may be relevant: http://sources.redhat.com/ml/binutils/2010-07/msg00260.html The assembler that we're using is based on binutils 2.20.51.0.2 which is circa the July, 2010 time frame.
