Regardless of removing the whole function later, this seems to be a good idea and should be reviewed/merged for backport benefit. |

9d65ad3 Clear vTxHashes when mapTx is cleared (Peter Bushnell) Pull request description: vTxHashes is a vector of all entries in mapTx, if you clear one you should clear the other, lest someone try to use the txiter in vTxHashes which would result in a segfault.

…r() helper fa818e1 txmempool: Remove unused clear() member function (MarcoFalke) Pull request description: Seems odd to have code in Bitcoin Core that is unused. Moreover the function was broken (see bitcoin/bitcoin#24145) and is brittle, as there is nothing that prevents similar bugs from re-appearing. Fix both issues by replacing it with C++11 member initializers.
