Merge bitcoin/bitcoin#21927: fuzz: Run const CScript member functions only once
fa74bfc8601cd2b749deb38388e2a4636d8b86ea fuzz: Run const CScript member functions only once (MarcoFalke)
Pull request description:
Those functions should be O(N) in the input size (or maybe worse, I didn't check), so if the fuzz input dictates to run them N times, the complexity is N^2.
Fix this by calling them only once.
Can be reviewed with: `--ignore-all-space --word-diff-regex=.`
Input: https://github.com/bitcoin/bitcoin/files/6464685/clusterfuzz-testcase-minimized-input.log
Hopefully fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=34101
