Heap management is mostly a RTL feature. For high TP compatibility, things like calling conventions must also match. IOW 8086 codegeneration is not automatically full TP compatibility on the binary level. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
