           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: unassigned@gcc.gnu.org
        ReportedBy: noloader@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:

See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
make: *** [asn.o] Error 1

===================================================================

Additional information

I modified Crypto++'s GNUMakefile a bit:

OLD:
    CXXFLAGS = -DNDEBUG -g O2
MOD:
    CXXFLAGS = -DNDEBUG -g -O2 -m32 -mtune=pentium4

When I invoked `make` I used the following:
    $ export PREFIX=/usr/local; make

$ g++ --version

For completeness, here's the function
(http://www.cryptopp.com/docs/ref/asn_8cpp_source.html):

00244 void OID::DEREncode(BufferedTransformation &bt) const
00245 {
00246         assert(m_values.size() >= 2);
00247         ByteQueue temp;
00248         temp.Put(byte(m_values[0] * 40 + m_values[1]));
00249         for (size_t i=2; i<m_values.size(); i++)
00250                 EncodeValue(temp, m_values[i]);
00251         bt.Put(OBJECT_IDENTIFIER);
00252         DERLengthEncode(bt, temp.CurrentSize());

00254 }

It looks like removing `-mtune=native` fixed it:

$cat GNUMakefile
...
ifneq ($(GCC42_OR_LATER),0)
ifeq ($(UNAME),Darwin)
CXXFLAGS += -arch x86_64 -arch i386
else
# CXXFLAGS += -march=native
endif
endif
...

The included source compiles OK for me with:

~/gcc-build/gcc/cc1plus -quiet -O2 -m32 -g -fstack-protector -march=prescott
-mtune=prescott --param l1-cache-size=16 --param l1-cache-line-size=64 --param
l2-cache-size=1024 asn.ii

Tried with:
GNU C++ (GCC) version 4.5.4 20110525 (prerelease)
GNU C++ (GCC) version 4.6.1 20110611 (prerelease)
GNU C++ (GCC) version 4.7.0 20110707 (experimental)

The bug is either fixed or local to:

g++ (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2

Please try to reproduce the bug with latest FSF compiler. Alternatively, please
report the bug to Ubuntu.

Interesting. If it matters, the hardware is a Dell GX280.

OK, thanks. The folks at Ubuntu are aware:

Thanks for the quick response and help.

I just tried using Fedora 15, which offers GCC 4.6 - OK.
