Memory leak issue when response headers are empty

[combinator]

What steps will reproduce the problem?

Create a client object . Submit request . If headers are empty, the script dies due to fatal error.

PHP Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes) in /var/www/app_root/vendor/yiisoft/yii2-httpclient/src/Response.php on line 62
PHP Fatal Error 'yii\base\ErrorException' with message 'Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes)'

in /var/www/app_root/vendor/yiisoft/yii2-httpclient/src/Response.php:62

Stack trace:
#0 [internal function]: yii\base\ErrorHandler->handleFatalError()
#1 {main}

What's expected?

Script should not generate any errors

What do you get instead?
