Crashing on M2 Mac

[Dan Friedman]

To all,

Oops!  I am mistaken…. It wasn’t MacOS that had the issue, it was iOS 17 that was problem.   iOS app built with 9.6.10 running on iOS 17 crashes when the convert command is called.  I can (in my experience) absolutely confirm this.  Debugged it down to the single line of code.  Rebuilt the app with 10.0.0 (dp 6) and the issue was solved.

Apologies for posting the wrong platform.

-Dan

Hello all,

We are not aware of any bug in the "convert" command, and I think it is
highly unlikely such a bug to affect M2 machines but not M1 ones.

We have a M2 machine running Sonoma which is used in the prerelease testing
so my feeling is that if there was such a bug, we would have caught it in
the prerelease testing of 9.6.11 rc1, which included a fix related to the
system date on Sonoma. Also, a related report we got about the convert
command - but turned out to be not a bug, is this one:

https://quality.livecode.com/show_bug.cgi?id=24362

BTW, the crash report that is attached in the first post indicates that the
app was running under Rosetta (> Code Type:X86-64 (Translated))

@Peter
If you have a reproducible recipe please do file a bug report and include
your app or a sample stack - I can give it a try in my Sonoma M2 mac mini.

Kind regards,
Panos
