Summary

validation_chainstate_tests/chainstate_update_tip crashes while activating the UTXO snapshot at src/test/validation_chainstate_tests.cpp:82-83.

The failure occurred in the Windows unit-test job for #7457:

• CI job: Windows unit tests
• Failure: Wine reports a page fault reading address 0x18 while CreateAndActivateUTXOSnapshot(this, NoMalleation, /*reset_chainstate=*/ true) is running.

Scope

This is reproducible on current develop at 2406ebcb9595dfa7ef03d38a72da50e758de30a1. The failing test file is not changed by #7457. The snapshot-helper call was already present on develop through the merged assumeutxo M1 work.

Reproduction

git checkout 2406ebcb9595dfa7ef03d38a72da50e758de30a1
make -C src -j8 test/test_dash
./src/test/test_dash -t validation_chainstate_tests/chainstate_update_tip --log_level=test_suite

Observed on macOS arm64:

Assertion failed: (!!s_active_handler), function sys_sig, file execution_monitor.ipp, line 739.
fatal error: in "validation_chainstate_tests/chainstate_update_tip": unrecognized signal
test/validation_chainstate_tests.cpp:83: last checkpoint

The same isolated test also crashes on the #7457 head, and the Windows CI run faults at the same checkpoint. Investigation should focus on the snapshot activation/reset path entered by CreateAndActivateUTXOSnapshot, not on #7457's EvoDB/chainstate-role delta.
