Crash in codesets library on the X5000 with MUIRoyale based Hollywood apps

Hello Friends,

I've been advocating for help getting this issue fixed in different forums for a while and thought I might try here. The short problem definition is that the amazing Hollywood application called Pixy crashed on the X5000, I personally have an AmigaOne XE where it runs just fine. I've asked 6 or 7 different X5000 owners and they all report the same issue, The SAM and X1000 owners have also reported no issues. There are a few other MUIRoyale based Hollywood apps that have the exact same problem so it is not just Pixy and it is easy to reproduce.

This particular problem is interesting as you have so many different tools at play it is easy for one author to pass it off as a problem outside the scope of their program.

I hope a solid Amiga dev with an X5000 is willing to take this on. The steps would be pretty simple, download the latest codesets, source code here, grab Pixy from the link above, and try it.

I am confident this person would see a DSI with a similar stack trace:

  26.     0x61727400 symbol not available

Then I think the next logical step would be to build the debug version of the codesets library with to see exactly what part of LIB_CodesetsConvertStrA is failing. Once that is known an issue could be raised on the github page to see if one of the team could address it.

Thanks for reading!

Re: Crash in codesets library on the X5000 with MUIRoyale...

If I hazard a guess it would be a corrupted string. It goes from LIB_CodesetsConvertStrA() into a newlib call. Decoding the newlib call is the hardest. Would help if there was a debug build.

Are you able to compile with Clib2? That at least gives function names. At least with my stuff. Provided I give -gstabs I see both source file, line and function.

Also, can you post the GPR dump and ASM listing? That usuallly tells exactly why it crashed. Usually a bad address can be easy to spot at times.

Re: Crash in codesets library on the X5000 with MUIRoyale...

The interesting thing about the problem is that only happens on the X5000. It will be exciting to see the exact issue so folks can noodle through why it's happening and why only on one platform.
