So this means that it's some odd random memory corruption that happens in one
scenario, not in another, because otherwise it should crash in both scenarios.

That's likely not enough - I'd need to be able to download your dive data from
dive logs.de as well in order to recreate that merge scenario that causes the
crash.
I had hoped that the offsets in the stack trace would be pointing me at a
specific line in the code, but at least the crash one is clearly bogus.
READ of size 4 at 0x000166f1de10 thread T0
#0 0x102c08efc in copy_dc_renumber+0x7a8 (Subsurface:arm64+0x100708efc)
#1 0x102c0404c in join_dive_computers+0xc8 (Subsurface:arm64+0x10070404c)
the copy_dc_renumber function isn't 0x7a8 or 1960 bytes long...
At first I thought maybe the compiler had inlined something there, but actually
that's way past the end of that object file...
I might be able to get something useful with a backtrace from a life app if I
can reproduce this locally.
And of course I should be able to instrument the build a bit more - which
always risks to hide the problem for things like this one...
The other thing that's (as always) annoying is that I tell the tooling not to
strip the binary, but somehow, somewhere, it gets stripped...
Dang.
I spent the last three hours on this flight trying to figure out how to get a
DMG that contains the debug symbols for the app - no such luck.
And while I figured out how to get at least a little bit of log info for apps
that crash when double clicked, using macOS' log app, I still can'f figure out
WH|Y it silently crashes when I double click, but doesn't crash when started
from the command line...
