Description
System: dual G4 powerMac running OS X 10.5.8
gfortran-mp-4.[89] fails to compile scipy/fftpack/src/fftpack/cfftb1.f when optimization is set to '-O3'. Reducing the optimization level to '-O2' allows the compilation to succeed. The attached file contains the relevant portion of the build log and a copy of cfftb1.f.
py(27|34)-scipy-0.14.0 built without incident with an earlier version of gcc-mp-4.8.
A quick workaround to get scipy to build is to modify the numpy file that sets the optimization level for the fortran compiler.
