   I stumbled upon a fuzz seed that oom’ed in CI for package_rbf. Since the seed appears to be too big to paste, I provide the output of $ base64 95a3b1b42d43ac7190f24ff116b2cd6515e7a566 > /tmp/base64-95a3b1b4-oom.txt: base64-95a3b1b4-oom.txt

   If the prior format is unsatisfactory, the problematic seed 95a3b1b42d43ac7190f24ff116b2cd6515e7a566 is also in this commit to qa-assets: https://github.com/bitcoin-core/qa-assets/pull/186/commits/8d624b44419f46bcb5117baa16047dbf4bdb339f

   It spends a long time hashing the large transaction, which has a large witness. The runtime is NUM_ITERS (aka 10'000) times n (size of the transaction), because the hashing is done in the loop.
