Description Ennio Barbaro 2010-10-18 17:52:48 UTC 
Hi all,

The attached code causes a segfault in gcc 4.5.1 (Debian 4.5.1-9), mabye an infinite recursion of decltype?

my system is a debian testing (kernel 2-6.32-5-amd64)

gcc configuration options:

Target: x86_64-linux-gnu                                                                                                      
Configured with: ../src/configure -v --with-pkgversion='Debian 4.5.1-9' --with-bugurl=file:///usr/share/doc/gcc-4.5/README.Bugs --enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --program-suffix=-4.5 --enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --with-gxx-include-dir=/usr/include/c++/4.5 --libdir=/usr/lib --enable-nls --enable-clocale=gnu --enable-libstdcxx-debug --enable-libstdcxx-time=yes --enable-plugin --enable-gold --with-plugin-ld=ld.gold --enable-objc-gc --with-arch-32=i586 --with-tune=generic --enable-checking=release --build=x86_64-linux-gnu --host=x86_64-linux-gnu --target=x86_64-linux-gnu                                  
Thread model: posix                                                                                                           
gcc version 4.5.1 (Debian 4.5.1-9)   

command line and output:
