Re: Best ways to free memory within c++ DLD's

[Jason Hoogland]

For the archives, the solution I found was not to include the -m64 when 
compiling Octave.  No performance loss, and no signs of memory leakage for 
very high numbers of iterations even without explicitely destructing 
variables in my DLD's.
