[Bug]: SIGSEGV on PHP 8.4.5 with opcache

[raf-lv]

Bug report

Environment

• PHP 8.4.5
• Laravel 11
• DataDog PHP Profiling Extension
• OPCache with JIT enabled (1235 mode)
• Environment: Laravel Queue Worker (artisan queue:work)

Issue Description

When running Laravel queue workers with DataDog profiling enabled, the PHP process crashes with a segmentation fault. The crash only occurs when memory allocation profiling is enabled. Disabling allocation profiling (DD_PROFILING_ALLOCATION_ENABLED: "false") resolves the issue.

Reproduction Steps

1. Run a Laravel queue worker with DataDog profiling enabled
2. Command used: php artisan queue:work sqs-non-fifo --sleep=3 --verbose --timeout=600 --queue=d
3. Process crashes with segmentation fault after some time

Stack Trace Analysis

The core dump reveals that the crash occurs in the stack walking functionality of the DataDog profiler, specifically while trying to collect a stack sample during memory allocation tracking:

Thread 1 (Thread 0x79266a4e4980 (LWP 105)):

Root Cause Analysis

The crash appears to occur when:

1. PHP/OPCache is performing memory allocation via _ecalloc()
2. DataDog's allocation profiler hooks into this allocation via alloc_prof_malloc()
3. The profiler attempts to collect a stack sample (collect_stack_sample()) to trace where the allocation is happening
4. Something in the stack walking code (line 257 of profiling/src/profiling/stack_walking.rs) causes a segmentation fault

The issue appears to be related to an interaction between:

• The DataDog allocation profiler
• OPCache JIT functionality (ir_sccp() from opcache.so is in the stack trace)
• PHP 8.4's memory model

Workaround

Adding the following environment variable resolves the issue by disabling allocation profiling:

DD_PROFILING_ALLOCATION_ENABLED: "false"

Additional Notes

1. The crash involves a segmentation fault (SIGSEGV) which suggests memory access violations
2. Based on frame Passing objects within span tags #16, the crash happens during OPCache JIT compilation phase (ir_sccp())
3. Given the crash occurs in a worker process, this could potentially impact production environments where queue workers are critical

[realFlowControl]

Hey @raf-lv 👋
thanks for this detailed bug report!
Could you help me reproducing this crash by:

• validating that it indeed does not crash when allocation profiling is enabled, but JIT is disabled
• post me the full stack trace please

The offending part seems to be:

dd-trace-php/profiling/src/profiling/stack_walking.rs

Lines 254 to 257 in c144bb0

	// SAFETY: if it's not null, then it should be valid
	// or something else has messed up already.
	let opline = unsafe { &*execute_data.opline };
	match opline.opcode as u32 {

[raf-lv]

hey @realFlowControl , I'll try without JIT soon.

Here's the full stack trace from gdb:

@realFlowControl ,

It seems disabling JIT also fixes the problem.

Hey @raf-lv 👋
I've talked with my colleague @bwoebi and we have an idea what could be triggering this. As we are currently not able to reproduce, I'd like to ask you if you could try out some things for us:

• enable JIT again (opcache.enable=1, opcache.enable_cli=1 and opcache.jit=1235) and set opcache.jit_hot_func to 0. This should deactivate the offending code path via zend_jit_hot_func() and not crash anymore, but also leave you without JITed functions. The main thing is: it would tell is if we found the right thing
• are you able to deploy a self-compiled version of PHP to validate a patch that we think should fix this crash? In case yes, I am preparing an upstream PR with a fix and will reference it here later.

If you need further assistance, you can find me also in Slack, in case it helps, we can also schedule a Zoom call via Slack

EDIT: this should be the upstream fix: php/php-src#18289

[raf-lv]

@realFlowControl thanks for following up.

• It seems adding opcache.jit_hot_func=0 also fixes the issue
• Will update soon with the self-compiled php

[bwoebi]

With the 1.8.3 release we now disable allocation profiling by default, if the jit is enabled. That should prevent this crash as well :-)
