[fpc-devel] Apple M1 processor

[C Western]

I have been trying out compiling my main application for the new Apple 
M1 machines, and have two queries:

The traceback on crashes does not include line numbers, when the same 
flags on other architectures does. Is this something that is easy to 
fix? Any pointers as to how?

Related to this I am trying to compile the rtl with debug information on 
by passing DEBUG=1 to the make install when compiling from the current 
SVN version, but it fails with:

...

/bin/mv -f aarch64/bin/aarch64-darwin/pp ppca64
/Applications/Xcode.app/Contents/Developer/usr/bin/make echotime
Start now 21:01:40
/usr/bin/diff ppc3 ppca64
Binary files ppc3 and ppca64 differ

I think a similar issue happens with other architectures on macs, and 
there I think it was possible to fix by adjusting the starting compiler, 
but I haven't been able to find a combination that works - any ideas?

My application works fine single threaded, but crashes occasionally when 
multi threaded, with what I think is some sort of memory corruption, but 
I haven't been able to pin this down yet, and fixing the above two 
points would help.
