Overview
| Comment: | [kennykb-numerics-branch] * generic/tclStrToD.c: Memory leak. 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. |
