Description

What happened?

Calling frankenphp.Init() followed by frankenphp.ExecuteScriptCLI() causes a segmentation fault (SIGSEGV).
Without Init(), the script runs but custom PHP functions registered by FrankenPHP (e.g. frankenphp_log) are undefined.

There is currently no working path to use ExecuteScriptCLI with FrankenPHP-registered PHP functions.

Minimal reproduction
go main package 
package main 

import (
	"os"

	"github.com/dunglas/frankenphp"
)

func main() {
	fp := "./file.php"

	frankenphp.Init()
	defer frankenphp.Shutdown()

	os.WriteFile(fp, []byte(`<?php
frankenphp_log("some message");`),
		0o755)
	status := frankenphp.ExecuteScriptCLI(fp, []string{fp})
	os.Exit(status)
}

$ go run -tags=nowatcher main.go
2026/04/15 12:27:02 INFO FrankenPHP started php_version=8.4.12 num_threads=28 max_threads=28
signal: segmentation fault

If the call to frankenphp.Init is omitted, then the following trace can be observed:

$ go run -tags=nowatcher main.go

Fatal error: Uncaught Error: Call to undefined function frankenphp_log() in /home/master/repo/sbc/src/ccm/goccm/tests/file.php:2
Stack trace:
#0 {main}
  thrown in /home/master/repo/sbc/src/ccm/goccm/tests/file.php on line 2
exit status 255
  • FrankenPHP version: v1.12.2
  • PHP version: 8.4.12
  • OS: Linux x86_64
Potentiak root cause analysis

From the GDB backtrace, the crash occurs in:

php_embed_init → php_tsrm_startup → ts_resource_ex → SIGSEGV

Looking at frankenphp.c, frankenphp_execute_script_cli spawns a new pthread and calls php_embed_init inside it.

Init() already calls php_tsrm_startup on the main thread. When execute_script_cli runs php_embed_init on a new pthread, TSRM is initialized a second time on a different thread → SIGSEGV.

Additionally, cli_script/cli_argc/cli_argv are unprotected global variables, which would also cause races under concurrent calls.

Research direction

Start with frankenphp.c, especially frankenphp_execute_script_cli, then trace the supplied Go reproduction through Init(), php_embed_init, and php_tsrm_startup. Reproduce the SIGSEGV with the shown command and verify that ExecuteScriptCLI works after Init(), custom functions such as frankenphp_log are available, and the reported global-state race is addressed.
