Program may set the RA_SIGN_STATE pseudo register by expressions. Libunwind expected only the DW_CFA_AARCH64_negate_ra_state could change the value of the register which leads to runtime errors on PAC enabled systems. In the recent version of the aadwarf64[1] a limitation is added[2] to forbid the mixing the DW_CFA_AARCH64_negate_ra_state with other DWARF Register Rule Instructions.
