Hi all, scipy.test(1,10) reports a lot of memory leaks, e.g. Getting factors of complex matrixswig/python detected a memory leak of type 'void *', no destructor found. Getting factors of real matrixswig/python detected a memory leak of type 'void *', no destructor found. Solve with UMFPACK: double precision complexswig/python detected a memory leak of type 'void *', no destructor found. swig/python detected a memory leak of type 'void *', no destructor found. ... ok Solve: single precision complexUse minimum degree ordering on A'+A. ... ok Solve with UMFPACK: double precisionswig/python detected a memory leak of type 'void *', no destructor found. swig/python detected a memory leak of type 'void *', no destructor found. ... ok Is this a swig problem ?
