There's memset() just above this line. It is completely useless - because the recv_buf will be overwritten straight away. I'm appending its removal to this patch.

retval = virStreamRecv(stream->stream, recv_buf, length); if (retval < 0) { - efree(recv_buf); - zval_dtor(zbuf); - ZVAL_NULL(zbuf); + zval_dtor(zbuf); + ZVAL_NULL(zbuf);

This space change does not look right.

} else { recv_buf[retval] = '\0';

Frankly, I've no idea whether this should be here. I feel like no because VIRT_ZVAL_STRINGL should not look into the recv_buf at any position greater than retval. That is why we give it the length of the string after all. Can you please check whether your case still works after this line is removed?

I'm dropping these curly braces around one line body.

RETURN_LONG(retval);

ACKed and pushed. Michal
