The latest version of MSVC causes an internal compiler error in src/test/fuzz/utxo_snapshot.cpp for both “Release” and “Debug” configurations:

According to Microsoft docs:

If the file has a cxxfe …, it is probably a parser error.

The issue also occurs in recent CI jobs using the image version 20241113.3.0.

It would be good to report this upstream, as requested in the error message. Possibly with a minimal reproducer, if someone on Windows can reduce it further.

@hebasto I have never buil the fuzzer before. Is the error from the build here?

Just configure with -DBUILD_FUZZ_BINARY=ON and build the fuzz target.

According to #27930 (comment) MSVC is including Bitcoin Core in an internal test-suite, but I guess they are not compiling the fuzz tests? cc @CaseyCarter

I see a -DBUILD_FUZZ_BINARY=ON in the setup, which suggests to me that we are at least building the fuzz tests. We are, however, at 0ca1d1b which seems to be about a month old. Our Real-World-Code projects don’t live at head, they jump forward periodically. If it’s a recent regression we may not have seen it yet.

I dug through the logs for yesterday’s nightly run, and the trunk compiler built utxo_snapshot.cpp just fine. I see: we onboarded bitcoin on 2024-10-22. It’s likely the 17.12 compilers have never seen it. Sorry about the regression; go ahead and file a report at https://developercommunity.visualstudio.com/cpp/report and we’ll see if we can get it serviced quickly.
