The file name string is already corrupted when Ffile_name_as_directory
is called; see below.
First, I rewrote the dynamic module[1] to add nonlocal exit checks after
almost every call to the module API.
[1]: https://gitlab.com/basil-conto/realpath
I also added the following assertions to src/emacs-module.c:

These reveal that value_to_lisp eventually returns a corrupted string,
but I don't know why. I've seen comments in src/fileio.c referring to
string-relocation during GC; could this be at play here? Either way, do
you have any suggestions on how to proceed?
Here's the full recipe again, now with debugging symbols for the module:
0. git clone https://gitlab.com/basil-conto/realpath.git
1. cd realpath
2. make DEBUG=1
3. cd /path/to/emacs/src
4. gdb emacs
5. set logging on
6. r -Q --module-assertions
7. (progn (module-load "/path/to/realpath.so")
(dotimes (_ 1000)
(realpath-truename user-emacs-directory)))
C-j
[The loop usually trips the assertions on its first run, but if it
doesn't, just try again once or twice.]
8. bt full
9. f 2
10. p p
11. pr [#<INVALID_LISP_OBJECT 0x03059c90>]
12. xpr
I attach the resulting GDB log.
Thanks,
