Hello, I am trying to compile the following code snippet: int main(int argc, char ** argv) { int stack_array[100]; stack_array[1] = 0; return stack_array[argc + 100]; // BOOM }
The followin CMakeLists.txt works fine, but you can notice that target_compile_options takes a list, while target_link_libraries takes a string. Always using the string will result in a compilation error, because the compiler flags are passed quoted to the compiler. Always using the list doesn't work either, because the generator expression is evaluated as $<1:-fsanitize=address -fno-omit-frame-pointer> and then passed as-is to the linker, which doesn't know what to do with it. Is this supposed to be like this? If yes, what's the rationale? Thanks in advance!
