This is coming from cffi (or in this case, pypy's bundled/modified copy):

Comment 3 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2023-12-02 13:17:57 UTC
I think it's a bug in pyzmq.

buildutils/_cffi.c has:

  typedef struct _zhint {
    void *sock;
    mutex_t *mutex;
    size_t id;
  } zhint;

zmq/backend/cffi/_cdefs.h has:

  typedef struct _zhint {
    void *sock;
    void *mutex;
    size_t id;
  } zhint;

Could you try what happens if you change the types to match?
Comment 4 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-12-03 04:17:59 UTC
Ugh.

zmq/utils/mutex.h contains a definition of `mutex_t`, but we can't include "mutex.h", because:
```
<cdef source string>:1:1: Directives not supported yet
```

And I can't just copy/paste `mutex_t` in because it uses:
a) pthread_mutex_t (which won't be defined, I imagine),
b) a conditional definition for windows as well rather than pthread_mutex_t...

so we need some solution in the build system and pass -D...? (like _cdefs.h does for ZMQ_FD_T?)
