I made the mistake of installing XCode 14 today,
at Apple's prompting and it completely broke the
exception handling in variouscomponents of my KDF9
emulation software.

I was able to get back to the previous release of XCode
from a backup, and things seem to be OK again.

At any rate, the regression tests are not failing any more.

I am using FSF gnat-12.1.0-1, and it seems that there
is now a gnat-12.1.0-2 release, but I do not see
anything there that is relevant to my problem.

Any insight anyone?
Why would an updated XCode have such a drastic effect?

If there's any C++ about, the troubles I had with GNT-LLVM[1] might
relate?

Well, I just tried, and it was different for me: both on Intel and Apple silicon any attempt to compile (or use git ...) failed dismally
somewhere in Xcode. On Apple silicon, I thought it was a failed update
so deleted Xcode and installed the command line tools, OK. Now, on
Intel, going to move Xcode out of the way ... and building with the
CLTs (version 14.0.0.0.1.1661618636) works fine.

C++ does not darken my doors. 8-)

Thanks for getting on this, Simon.

I have now deleted even the older XCode and things continue OK,
now withgnat-12.1.0-2.

How can I find out the version number of the CLTs?

Well, I spoke too soon.
Sometime between last night and this morning it reverted to non-working!

Same problem: compiled programs collapse when an exception is raised.

I have deleted and re-installed the CLTs using xcode-select, but no joy. Snookered!

Thanks, version 14.0.0.0.1.1661618636 is what I have.

I got back to sanity by restoring
/Library/Developer/CommandLineTools/usr/bin
from a backup.

The (working) tools in there are over a year old.
I wonder what Apple did to bork them with XCode 14.

Just re-ran ACATS 4.1Y - abandoned after this:

Turns out you have to actually *run* the new Xcode (and make the default
choice of components) for it to install its version of the CLTs,
including git.

So, having run XCode, do you get the exception failure with the new CLTs?

Short answer: yes, fraid so.

Looks as though 14.1 is going to have the same problem (given that the
beta has). But we might be lucky.

(/Library/Developer/CommandLineTools contains a subset of the equivalent
/Applications/Xcode.app)
