[Bug] `core_tests` failed on linux about monero HOT 13 OPEN

Can you enable the log and put here the detailed output? I believe something like this would do it for you after building:

$ctest -R core_tests --debug

Can you start core_tests in gdb and share a backtrace?

from monero.

Two other things I am suspicious of.

1. Running core_tests without any initialization, I believe does not work. For example, if I run ./core_tests it does print:

$ >> ./core_tests 
2023-12-26 08:35:04.770	E Wrong arguments

3. When you run ctest -R core_tests --debug it should dump much more dump than only CMake. I f the core_tests runs. This means for some reason it gets SIGSEGV at the very beginning.

from monero.

Before I check with gdb, I changed the build option CMAKE_BUILD_TYPE to Debug, it gave me the expected test output.

cmake -GNinja -S. -Bbuild -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTS=ON && cmake --build build

The core_tests --generate_and_play_test_data finally produce the right output.

Without the flag, the backtrace is

Reading symbols from ./core_tests...done.

How about change this part

if(BUILD_DEBUG_UTILITIES)
  add_subdirectory(debug_utilities)
endif()

into

if(BUILD_DEBUG_UTILITIES OR BUILD_TESTS)
  add_subdirectory(debug_utilities)
endif()

from monero.

This doesn't look like correct to me. Can you use list command in gdb to show which line exactly the SIGSEGV happens?

It still doesn't make sense to me. Looks like a linking/library issue for some reason. I will take a look at this.
