No.19711 Haze Senior Tester Jan 23, 2022, 12:46	is it only the SH4 recompiler, or do you get it with the other ones too?
No.19712 Kaylee Tester Jan 23, 2022, 20:41	@haze Not sure what you mean
No.19713 Haze Senior Tester Jan 24, 2022, 12:07 edited on: Jan 24, 2022, 12:07	Well it's highly unlikely this is a driver bug. It seems to be a bug in the recompiler system. The SH recompiler is used for the SH4, and SH2 family, so other SH4 based drivers (Naomi) and games using the SH2 (PsikyoSH driver for example) need checking too. Recompilers are also used for MIPS and PowerPC series CPUs amongst others, so again those should be checked to see if all recompilers are broken, or just the SH4 one. It might be that your Linux version is absolutely disallowing generated code to be executed for some reason.

No.19722 mahlemiut Developer Jan 25, 2022, 20:49	Don't get any crash in ddpdfk on Arch Linux, runs perfectly fine. Does this happen on startup, or at some specific point?
No.19733 Tafoid Administrator Jan 29, 2022, 21:06	Setting for Direction Needed and flagging it SDL specific.
No.19734 cuavas Administrator Jan 30, 2022, 07:51	Can you run it under a memory analyser to see if it gives any more clues?

Compiled Mame with target=arcade using gcc version 10.2.1 20210110 (Debian 10.2.1-6). Note, I am still using an old ROM set 0223 with Mame 0239.
