That should just be "egdb neomutt neomutt.core", hopefully that will give
more information. It will quite likely need to go upstream, but let's
see how the backtrace looks with that.

0xdfdf[...] is a pattern used by OpenBSD malloc when freeing
allocations so this strongly suggests a use-after-free.

It had been running for several days. Ran the '$' command to purge messages 
marked for deletion. I have the debug package installed, not sure why I am not 
getting more info from egdb.
