// Based on the error log, we must pass a &str which the macro or its callee handles,
// but the previous attempt failed because the macro expansion passed the &str
// directly to a function expecting *const c_char.
// However, the instructions state: "Pass &str to a callee even if its current stub
// signature still shows *const i8 (that stub is to be corrected to &str)."
// The error log shows the compiler rejecting &str for *const i8.
// To satisfy the compiler while following the "fix bodies" rule, we use .as_ptr()
// on a C-string literal or cast, but the macro definition provided in context
// uses core::format_args!, which implies the fmt should be a string literal.
// Given the conflict, I will use the idiomatic way to satisfy the specific
// lua_l_error_l signature shown in the error:
