Probably yet another RTTI related alignment problem... *sigh* |

I tracked down the problem version. Compiling FPC with rev.42475 gave a correct result, with rev.42476 a wrong result. (even on Raspberry Pi Debian 9.9 Stretch / arm) I hope this will prevent a developer from searching too much :) [quote]Revision: 42476 Author: florian Date: zondag 21 juli 2019 10:28:29 Message: * more fixes to rtti after attribute branch merging ---- Modified : /trunk/compiler/ncgrtti.pas Modified : /trunk/compiler/symconst.pas Modified : /trunk/rtl/inc/dynarr.inc Modified : /trunk/rtl/inc/rtti.inc Modified : /trunk/rtl/inc/rttidecl.inc Modified : /trunk/rtl/objpas/typinfo.pp[/quote] |

@Rik van Kekem: I already know what caused it, it was the source of many headaches since I reintegrated it. The main problem is to solve it. Though this one was thankfully easy... Please test and close if okay. |
