However, a bug caused the optimiser to incorrectly apply this same logic to `LOADI $i, dest` instructions, mistakenly interpreting the immediate value (`$i`) as a register ID. This version fixes this optimisation bug. As a result, parsing and compiling long lists with distinct elements (e.g., `1..100`) can now finally be completed without crashing! + + ```c + int CmEnv_Optimise_check_occurence_in_block(int localvar, + int target_imcode_addr) { + ... + + case OP_LOAD: + case OP_LOADI: + // OP src1 dest + if (imcode->operand1 == localvar) { + return 1; + } + break; + ==> + case OP_LOAD: + //case OP_LOADI: + // OP src1 dest + if (imcode->operand1 == localvar) { + return 1; + } + break; + + ``` + + + ### v0.13.2 (released on 16 March 2026) #### Polished |
