Here it is.

Reading symbols for shared libraries . done
octave:1> strptime ('09/13', '%m/%d')
Reading symbols for shared libraries . done

Program received signal EXC_BAD_ACCESS, Could not access memory.

I'm presently building with the debug information as well.

Unfortunately, the configure process didn't work as before. So I'm not  
sure how useful that will be.

configure: running /bin/sh ./configure '--prefix=/sw'  '--infodir=$ 
{prefix}/share/info' '--mandir=${prefix}/share/man' '--libexecdir=$ 
{prefix}/lib' '--build=i386-apple-darwin' '--with-blas=/sw/lib/ 
libatlas.a' '--with-lapack=/sw/lib/libatlas.a' 'build_alias=i386-apple- 
darwin' 'CFLAGS=-O2 -g' 'LDFLAGS=-L/sw/lib' 'CPPFLAGS=-O2 -g'  
'CXXFLAGS=-O2 -g' 'F77=/sw/bin/g95' 'FFLAGS=-O2 -g' --cache-file=/dev/ 
null --srcdir=.

Octave is now configured for i386-apple-darwin

   Source directory:     .
   Installation prefix:  /sw
   C compiler:           gcc  -mieee-fp  -Wall -W -Wshadow -O2 -g
   C++ compiler:         g++  -mieee-fp  -Wall -W -Wshadow -Wold-style- 
cast -O2 -g
   Fortran compiler:     /sw/bin/g95 -O2 -g
   Fortran libraries:    -L/sw/bin/../lib/gcc-lib/i386-apple- 
darwin8/4.0.3 -lf95
   BLAS libraries:       /sw/lib/libatlas.a -Wl,-framework -Wl,vecLib
   FFTW libraries:
   GLPK libraries:
   UMFPACK libraries:
   AMD libraries:        -lamd
   CAMD libraries:       -lcamd
   COLAMD libraries:
   CCOLAMD libraries:
   CHOLMOD libraries:
   CXSPARSE libraries:
   HDF5 libraries:
   CURL libraries:       -lcurl
   REGEX libraries:
   QHULL libraries:	
   LIBS:                 -lreadline  -lncurses -lz -lm
   Default pager:        less
   gnuplot:              gnuplot

   Do internal array bounds checking:  false
   Build static libraries:             false
   Build shared libraries:             true
   Dynamic Linking:                    true (dyld)
   Include support for GNU readline:   true
   64-bit array dims and indexing:     false

To be sure I got the debug info, I placed '-g' on all compiler  
options ... can that cause so many libraries to turn up missing?
