7946,ICE on Cygwin (gcc 4.5.3) when Phoenix v3 is used,Andrey Semashev,Joel de Guzman,"While building Boost.Log (trunk revision 822) against Boost (branches/release revision 82662) on Cygwin with gcc 4.5.3 the compilation fails with the following errors:

{{{
./boost/spirit/home/qi/nonterminal/rule.hpp:184:9: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
}}}

The complete build log is attached. The problem may be related to the fact that Boost.Log uses Boost.Phoenix v3 for its expressions, so it defines the BOOST_SPIRIT_USE_PHOENIX_V3 macro while building.

Boost.Log can be checked out from SVN trunk:

svn co https://boost-log.svn.sourceforge.net/svnroot/boost-log/trunk/boost-log boost-log

The relevant directories have to be put into the Boost tree, then the library can be compiled with the following command:

{{{
./bjam-cyg.exe -j 8 ""cxxflags=-std=gnu++0x"" toolset=gcc variant=debug target-os=cygwin logapi=unix threading=multi threadapi=pthread link=shared runtime-link=shared --with-log stage
}}}

where bjam-cyg.exe is bjam built under Cygwin. The problem is also present without the -std=gnu++0x switch.
