我目前正在做一个项目，使用 cling 来编译文件。但是，我在构建项目时遇到了分段错误。
LLVM 似乎是原因。
我尝试过使用 Cmake 包含 Cling 和 LLVM。对于 Cling，它似乎可以工作，但 LLVM 在应用程序启动时会出现段错误。我已经按照文档中的说明包含了 LLVM，但没有运气：/我在 github 上
看到这篇文章
说要用 LLVM 替换 ${llvm_libs}
然后，它终于编译了，但在应用程序启动时出现了段错误。
这是 valgrind 的输出：

这是我们使用的用于 Cling 和 LLVM 包含的最小 Cmake：
set(OPT "-Wall -Werror -std=c++17 -g -DLLVMDIR='\"/usr/include/llvm/\"'")
find_package(Cling REQUIRED)
find_package(LLVM REQUIRED CONFIG)
message(STATUS "Found LLVM ${LLVM_PACKAGE_VERSION}")
message(STATUS "Using LLVMConfig.cmake in: ${LLVM_DIR}")
message("LLVM_INCLUDE_DIRS=${LLVM_INCLUDE_DIRS}")
message("LLVM_DEFINITIONS=${LLVM_DEFINITIONS}")
target_include_directories(${OUTPUT} ${CLING_INCLUDE_DIRS})
include_directories(${LLVM_INCLUDE_DIRS})
add_definitions(${LLVM_DEFINITIONS})
# Find the libraries that correspond to the LLVM components
# that we wish to use
llvm_map_components_to_libnames(llvm_libs support core irreader)
target_link_libraries(${OUTPUT} ${CLING_LIBRARIES} LLVM stdc++fs)
在达到主要功能之前似乎失败了。在这一点上，我们甚至没有包含任何用于 cling 或 LLVM 的头文件，但它仍然失败了。这是 LLVM 的已知错误还是我遗漏了什么？
