I'm assuming that you are using the signed data content type since you mention PKCS7_verify(). Is this the clear signed content (multipart/signed) or opaque? One of the problems is that the ASN1 code has to keep all its data in memory, changing that isn't easy and so far there hasn't been much interest. There is some experimental code in OpenSL 0.9.8-dev which will handle single pass processing of the clear signed type which may help: because the content isn't part of the ASN1 structure it can do that.
