Bug description:
  I was attempting to compile the latest Crypto++ (svn checkout
  https://cryptopp.svn.sourceforge.net/svnroot/cryptopp/trunk/c5 cryptopp) on a
  Dell GX280 (32 bit Pentium 4). Here's the internal compiler error:

  $ make
  g++ -DNDEBUG -g -O2 -march=native -pipe -c 3way.cpp
  g++ -DNDEBUG -g -O2 -march=native -pipe -c adler32.cpp
  g++ -DNDEBUG -g -O2 -march=native -pipe -c algebra.cpp
  g++ -DNDEBUG -g -O2 -march=native -pipe -c algparam.cpp
  g++ -DNDEBUG -g -O2 -march=native -pipe -c arc4.cpp
  g++ -DNDEBUG -g -O2 -march=native -pipe -c asn.cpp
  asn.cpp: In member function ‘void
  CryptoPP::OID::DEREncode(CryptoPP::BufferedTransformation&) const’:
  asn.cpp:254:1: error: unrecognizable insn:
  (insn 194 178 195 2 asn.cpp:248 (set (reg:SI 2 cx)
          (mem:QI (plus:SI (reg/f:SI 1 dx [orig:61 D.44160 ] [61])
                  (const_int 4 [0x4])) [16 S1 A32])) -1 (nil))
  asn.cpp:254:1: internal compiler error: in extract_insn, at recog.c:2104
  Please submit a full bug report,
  with preprocessed source if appropriate.
