Thanks, can you run Emacs 29 under a debugger and show a backtrace

when it crashes?

Unfortunately, I don’t have a C development environment setup on my little MacBook (and haven’t used gdb for more than 20 years besides).

Backtrace from LLDB will be also helpful.  Without a crash backtrace,

we will have to wait until someone can reproduce the crashes on a

system where a debugger _is_ available.

It took me a while to get lldb to run emacs (missing get-task-value entitlement), and then:

running under lldb, emacs doesn’t crash, but it also doesn’t open any

frames:

Could you please tell which LLDB this is

     lldb --version

and how you installed it?  The missing entitlement is strange.

lldb --version

lldb-1205.0.27.3

Apple Swift version 5.4 (swiftlang-1205.0.26.9 clang-1205.0.19.55)

I didn’t install lldb itself, but I assume it was installed together with the Xcode command line tools.

The entitlement seems to be a frequent issue but it is very hard to find in DuckDuckGo.

lldb /Applications/Emacs-28.2.app/Contents/MacOS/Emacs

 (lldb) target create "/Applications/Emacs-28.2.app/Contents/MacOS/Emacs"

 Current executable set to

 '/Applications/Emacs-28.2.app/Contents/MacOS/Emacs' (arm64).

 (lldb) run

 Process 22971 launched: '/Applications/Emacs-28.2.app/Contents/MacOS/Emacs' (arm64)

 Process 22971 exited with status = 0 (0x00000000)

 (lldb) ^D

This looks correct to me. 

Except for Emacs exiting without doing anything?
