Also reacted to this, but another bonus of having the intermediate `test_temp` dir is that one doesn't unintentionally flood an already existing directory with directories based on test-names.

I was unable to reproduce the error that @maflcko reported.

Analyzing the line, I don’t see how the content of the parentheses could ever become negative. At most, it would become temporary negative, when `max_spendable` and `max_output_groups` have already been deducted, but `group_pos.size()` has not yet been added.

Would it perhaps help if the addition were put to the front so it never even temporarily goes negative?

May address the problem reported by @maflcko in https://github.com/bitcoin/bitcoin/pull/27877#pullrequestreview-1890304914.

For some values, `MAX_MONEY - max_spendable - max_output_groups` could result in a partial negative value. By putting the addition of `group_pos.size()` first, all partial results in this line will be strictly positive.

I opened this as a draft, since I was unable to reproduce the issue, so I’m waiting for confirmation whether this in fact mitigates the problem.

I was able to reproduce if I enabled the integer sanitizer.

After @achow101 pointed out that I needed to enable the "integer" fuzz sanitizer, I was able to reproduce the issue and verify that the proposed fix mitigates the problem.

Thanks, I guess I misinterpreted `SUMMARY: UndefinedBehaviorSanitizer: implicit-integer-sign-change ../../src/wallet/test/fuzz/coinselection.cpp:161:89 in` as needing the "undefined" sanitizer, but didn’t realize that there was one for "integer". I was able to reproduce and verify that changing the order of operations mitigates the issue here.

I think this check is specifically done to see if the block is pruned, hence the error message `(pruned data)`. This is taken verbatim from the above function, `GetBlockChecked`, which all it does inside the locked block is check if it is pruned or not. Here we also extract the `FlatFilePos`. However, if `blockindex.nStatus & BLOCK_HAVE_DATA` is `false` then the call to `ReadRawBlockFromDisk` will fail and throw the message `Block not available`. The first commit addresses the undefined behavior
