[petsc-dev] memory leaks in BCGSL when using KSPReset()

After adding this test in petsc4py-dev/test/test_ksp.py :

    def testResetAndSolve(self):
        self.ksp.reset()
        self.testSolve()
        self.ksp.reset()
        self.testSolve()
        self.ksp.reset()

it seems there is some memory bleeding:

[0]Total space allocated 256 bytes
[ 0]80 bytes KSPSetUp_BCGSL() line 476 in
/home/devel/petsc/dev/src/ksp/ksp/impls/bcgsl/bcgsl.c
      [0]  KSPSetUp() line 184 in
/home/devel/petsc/dev/src/ksp/ksp/interface/itfunc.c
      [0]  KSPSolve() line 332 in
/home/devel/petsc/dev/src/ksp/ksp/interface/itfunc.c

These are workspace arrays that are re-allocated at every KSPSetup_BCGSL call.

Not sure about the proper way to fix this, but I would deallocate the
arrays at KSPReset_BCGSL. Can anyone help me with this?


PS: Will we ever have petsc4py in the nightly builds? Is there
something to be done from my side?
