My environment

mailparse version is 3.1.6. PHP 8.2.9 on Ubuntu on multipass(M2 macOS).

$ sapi/cli/php -v
PHP 8.2.9 (cli) (built: Aug 28 2023 11:42:56) (NTS DEBUG)
Copyright (c) The PHP Group
Zend Engine v4.2.9, Copyright (c) Zend Technologies

Note: My PHP configure option is included --enable-debug.

$ sapi/cli/php -i | grep 'configure'
Configure Command =>  './configure'  '--enable-debug' '--enable-mbstring' '--enable-mailparse' '--prefix=/home/ubuntu/php-8.2

Expected

No output SIGSEGV.

Sorry, but cannot reproduce with 8.2 or 8.3

Please provide full gdb backtrace

[youkidearitai]

@remicollet Thanks for reply!

Please provide full gdb backtrace

Sorry, I can't reproduced on gdb on make test. I put in php-src/ext to mailparse directory. The usual phpize command is not reproduced.

cd /path/to/php-src
git clone https://github.com/php/pecl-mail-mailparse ext/mailparse
./buildconf -f
./configure --enable-debug --enable-mbstring --enable-mailparse # Compile php-src 
make
make test TESTS=ext/mailparse
tail ext/mailparse/tests/006.out

[youkidearitai]

I tried dump file from gdb backtrace.
