[SciPy-dev] UMFPACKv4.4 and swig memory leak of type 'void *'

[Nils Wagner]

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 ?
