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:

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:

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

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

$cat GNUMakefile

ifneq ($(GCC42_OR_LATER),0)

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

The work around is to compile without -march=prescot. The fault was introduced in gcc-linaro-4.5-2011.03-0. It does not exist in gcc-linaro-4.6-2011.06-0, gcc 4.5, gcc 4.6, or gcc trunk r176133.

I've set it to medium priority as it is a ftbfs and has a work around.
