PCRE JIT allocation error when compiling PHP <= 8.0 on macOS 15 (Apple Silicon M4)

[adeshmrane]

Description

I'm trying to compile PHP 8.0.30 (and earlier versions) on macOS 15 Sequoia, running on an Apple Silicon M4 chip.

During the build process, I encountered the following fatal error related to PCRE JIT memory allocation while generating phar.phar:

Fatal error: Uncaught InvalidArgumentException: RegexIterator::__construct(): Allocation of JIT memory failed, PCRE JIT will be disabled. This is likely caused by security restrictions. Either grant PHP permission to allocate executable memory, or set pcre.jit=0 in /Users/pc/Desktop/nsetup/setups/src/php-8.0.30/ext/phar/phar.php:1133 Stack trace:
#0 /Users/pc/Desktop/nsetup/setups/src/php-8.0.30/ext/phar/phar.php(1133): RegexIterator->__construct(Object(RecursiveIteratorIterator), '/\\.svn/')

#4 {main} thrown in /Users/pc/Desktop/nsetup/setups/src/php-8.0.30/ext/phar/phar.php on line 1133 make: *** [ext/phar/phar.phar] Error 255

Steps to Reproduce:

1. Download PHP 8.0.30 source from php.net
2. Run the following configuration on macOS 15 (M4):
   ./configure --with-iconv=shared,/Applications/AMPPS/apps && make
3. Compilation fails when building phar.phar

This issue does not occur when compiling PHP 8.1 or newer on the same system.

PHP Version

PHP 8.0.30

Hi

Please note that PHP 8.0 is no longer supported, neither for security fixes nor for bugfixes.
The lowest support security fix branch is PHP 8.1, and the lowest supported bugfix branch is PHP 8.3.
Please retry on PHP 8.3.

Hi,

Thank you for the quick response.

I understand that PHP 8.0 is no longer supported, and that PHP 8.1+ is the minimum maintained branch.

That said, I’m trying to compile PHP 8.0 on macOS 15 (Apple Silicon M4) for legacy reasons, and I’m wondering if there’s any known workaround or unofficial patch to bypass the PCRE JIT memory allocation issue during the phar.phar build?

As mentioned earlier, this issue does not occur when compiling PHP 8.1 or newer on the same system — PHP 8.3 builds without any problem.

Any pointers for a workaround would be appreciated, even if unsupported.

Thanks again!

Ah I missed this part of the report.

Any pointers for a workaround would be appreciated, even if unsupported.

Please try cherry-picking f8b217a

@nielsdos eventually ; would --with-external-pcre configure setting help assuming the packaged pcre installed is recent enough ?

This could also work, but may also have some behavioural change. OP can try both options.
