Hi Thomas,

Not yet ... in fact, I don't even know how to do that. Please advise.

In the event, you might spot something, the Fink build is equivalent to

#! /bin/sh
#./autogen.sh
./configure --prefix=/sw  'FLIBS=/sw/lib/gcc4.2/lib/libgfortran.dylib'  
'F77=/sw/bin/gfortran' '--infodir=${prefix}/share/info' '--mandir=$ 
{prefix}/share/man' '--libexecdir=${prefix}/lib' '-enable-shared' '- 
enable-dl' '--disable-static' '--without-mpi' '--with-hdf5' '--with- 
fftw' '--with-lapack=-Wl,-framework,Accelerate,-dylib_file,/System/ 
Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/ 
vecLib.framework/Versions/A/libLAPACK.dylib:/System/Library/Frameworks/ 
Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ 
libLAPACK.dylib' '--with-blas=-Wl,-framework,Accelerate,-dylib_file,/ 
System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/ 
vecLib.framework/Versions/A/libBLAS.dylib:/System/Library/Frameworks/ 
Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ 
libBLAS.dylib' 'CFLAGS=-O3' 'LDFLAGS=-L/sw/lib' 'CPPFLAGS=-I/sw/ 
include' 'CXXFLAGS=-O3' 'FFLAGS=-O3' --cache-file=/dev/null --srcdir=.
make
make check

I tried changing the optimization to -O0, but that was even worse :- 
( ... the result is below.

../run-octave --norc --silent --no-history ./fntests.m .

Integrated test scripts:

   src/DLD-FUNCTIONS/bsxfun.cc ............................panic: Bus  
error -- stopping myself...

I'll try to compile again with debugging enabled (I'll add "-g" to the  
*FLAGS).
