Summary: internal compiler error: in extract_insn, at recog.c:2104 Product: gcc Version: 4.5.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: noloa...@gmail.com Sorry if this was previously reported. Searching returned an error stating I used an invalid file extension. 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: $ export PREFIX=/usr/local; make g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c 3way.cpp g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c adler32.cpp g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c algebra.cpp g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c algparam.cpp g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -march=native -pipe -c arc4.cpp g++ -DNDEBUG -g -O2 -m32 -mtune=pentium4 -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.
