Bug#388626: g++-4.1: ICE on source with template

Package: g++-4.1
Version: 4.1.1-5
Severity: normal

Debian (testing) g++-4.1 fails to compile a simple C++ source that makes
use of templates and quits with an internal compiler error:

$ g++-4.1 -Wall -c gcc-4-bug.ii
gcc-4-bug.cc: In function ‘int label(int) [with bool neighb8 = true]’:
gcc-4-bug.cc:21: internal compiler error: in make_decl_rtl, at varasm.c:883
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
For Debian GNU/Linux specific bug reporting instructions,
see <URL:file:///usr/share/doc/gcc-4.1/README.Bugs>.
Preprocessed source stored into /tmp/ccANp0rz.out file, please attach this to your bugreport.

The stripped down and preprocessed source that's used to demonstrate the
error ('gcc-4-bug.ii') is attached to this mail.

As a workaround, the source can be compiled using g++-3.4, but that
might cause trouble when other C++ libraries are linked into the
resulting executable (ABI incompatability).

Note that compilation with g++-4.0 fails as well.
