The bug

error: ld.lld: relocation R_X86_64_TPOFF32 against debug.panic_stage cannot be used with -shared

It's referring to the threadlocal variable.

/// Counts how many times the panic handler is invoked by this thread.
/// This is used to catch and handle panics triggered by the panic handler.
threadlocal var panic_stage: usize = 0;

Will need to investigate why this doesn't work.

Workaround

• Do a ReleaseSafe or ReleaseFast build, for libraries like SDL2, just build as "ReleaseSafe" when doing "Debug" build.
