 Try using guardmalloc(3) and malloc_history(1) to find the issue.

 Well, maybe or not. What I can say is that before the latest GCC stuff,
 octave-devel worked just fine building and executing. After the GCC
 changes, we're struggling to build it, or it does not execute if it does
 build. The Octave source itself did not change; nor did its Portfile. The
 only thing that has changed in the past few days is the GCC dependency.  I
 do not know if it is libstdcxx or gcc that's the issue, or maybe some
 combination; but, I highly doubt it's octave itself. If my latest rebuild
 doesn't work, I'll try using the mixed Apple gcc/g++ and MacPorts fortran
 approach.
