ERROR: kevent() failed: Bad file descriptor on macOS 14.5

[barkingfoodog]

I'm trying to use pl/sh with PostgreSQL 16.4 on macOS 14.5. I'm linking against the MacPorts installation of PostgreSQL. pl/sh compiles and installs OK, but I get an error trying to use it:

# DO E'#!/bin/bash\nwhoami' LANGUAGE plsh;
ERROR:  kevent() failed: Bad file descriptor
FATAL:  terminating connection because protocol synchronization was lost
PANIC:  proc_exit() called in child process
SSL error: decryption failed or bad record mac
The connection to the server was lost. Attempting reset: Succeeded.
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, compression: off)

Is pl/sh compatible with macOS? My C and system programming is pretty rusty, but I'm happy to debug further or test a fix.

Here is the macOS crash report.
