+* Bugs in gcc 3.0 triggered
+
+According to a problem report, there are bugs in gcc 3.0 that are
+triggered by some of the code in OpenSSL, more specifically in
+PEM_get_EVP_CIPHER_INFO().  The triggering code is the following:
+
+       header+=11;
+       if (*header != '4') return(0); header++;
+       if (*header != ',') return(0); header++;
+
+What happens is that gcc might optimize a little too agressively, and
+you end up with an extra incrementation when *header != '4'.
+
+We recommend that you upgrade gcc to as high a 3.x version as you can.
