Comment in TclSetBignumIntRep + * generic/tclObj.c: indicates that mp_init() is called on the + bignumValue argument to clear it, while keeping the digits array + transferred to the interp of the Tcl_Obj. The implication is that + callers of TclSetBignumIntRep() (and their callers) need not call + mp_clear(), but can imagine they've transferred ownership of an + mp_int value to Tcl. However, mp_init() doesn't merely re-initialize + the fields of an mp_int to hold the value zero. It also allocates + a fresh dp array of minimum size governed by MP_PREC. Without a + corresponding mp_clear() call somewhere, these dp arrays are leaked. + Added some mp_clear() calls to fix the leak, but better fix strategies + should still be pursued. Perhaps the best approach is to just + invade the mp_int struct and do the necessary surgery ourselves. + 2005-09-20 Don Porter <dgp@users.sourceforge.net> [kennykb-numerics-branch] |
