I’m working on a compiler project based on LLVM and encountering an issue when trying to debug my unit tests using LLDB-17. The debugger crashes with a floating point exception both in VSCode and from the command line. Interestingly, LLDB-17 works fine with another project.
Here are the details of the crash:
