I have a file that crashes my emacs-26 on Mac every time:
[-- Attachment #2: out.xz --]
[-- Type: application/octet-stream, Size: 5700 bytes --]
[-- Attachment #3: Type: text/plain, Size: 8318 bytes --]
However, this doesn't happen when I start with emacs -Q. Here's the stack
trace from the failure. It continues like this for thousands of repeating
lines until aborting.
I can help debug it under lldb, if you can tell me what to look for.
John

Another strange data point: if I xzip the file and then open /tmp/out.xz, I
can read the file. Emacs only crashes if I try to open the uncompressed file.

First thing to look for is which of the 3 recursive calls to
substitute_object_recurse are taken?
The next question is where in the problematic file are we reading when
the infinite recursion happens? This could be easier to establish
starting at read_internal_start in frame 203820 (where you can see
what is 'stream').
