CaBundle openssl 内存泄露问题
mmap() failed: [12] Cannot allocate memory
PHP Fatal error: Out of memory (allocated 81788928) (tried to allocate 14987979559889010744 bytes) in phar:///usr/local/bin/composer/vendor/composer/ca-bundle/src/CaBundle.php on line 167
openssl_x509_parse调用之后内存泄漏
$x509data = file_get_contents ( “d:/certs/xxx.cer” );
$resource = openssl_x509_read ( $x509data );
$certdata = openssl_x509_parse ( $resource ); //<=就是这句有问题
echo $certdata [‘serialNumber’]; //<=就是需要这个数据所以要调上面那句
echo $x509data;
unset($certdata); //<=似乎没有什么用
openssl_x509_free($resource); //<=似乎没有什么用x2
循环个100000次可以看到明显一直在涨。
windows下试过php5.4+openssl0.9.8，php7.0+openssl1.0.2都有这问题。

==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
/usr/local/etc/openssl@1.1/certs
and run
/usr/local/opt/openssl@1.1/bin/c_rehash
openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because macOS provides LibreSSL.
If you need to have openssl@1.1 first in your PATH run:
echo ‘export PATH=”/usr/local/opt/openssl@1.1/bin:$PATH”’ » /Users/didi/.bash_profile
For compilers to find openssl@1.1 you may need to set:
export LDFLAGS=”-L/usr/local/opt/openssl@1.1/lib”
export CPPFLAGS=”-I/usr/local/opt/openssl@1.1/include”
For pkg-config to find openssl@1.1 you may need to set:
export PKG_CONFIG_PATH=”/usr/local/opt/openssl@1.1/lib/pkgconfig”

高版本问题是和php7.0 不兼容
低版本内存泄露
