The Cobol compiler has been updated to fix a use-after-free error by ensuring that the arith_t structure is constructed by value and that reference lists are initialized rather than copied. Additionally, the compiler now validates that the ADD CORRESPONDING statement accepts exactly two operands, addressing a known issue and preventing an internal compiler error (ICE) for WRITE statements in syntax-only mode.
