Package: libv8
Version: 3.7.12.22-3
Severity: important
Tags: sid wheezy
User: debian-...@lists.debian.org
Usertags: ftbfs-gcc-4.7
The package fails to build in a test rebuild on at least amd64 with
gcc-4.7/g++-4.7, but succeeds to build with gcc-4.6/g++-4.6. The
severity of this report may be raised before the wheezy release.
../src/string-search.h:401:3: error: assuming signed overflow does not occur
when assuming that (X + c) < X is always false [-Werror=strict-overflow]
The full build log can be found at:
http://people.debian.org/~lucas/logs/2012/03/29-clang-gcc47/unstable-gcc47/libv8_3.7.12.22-3_unstable-gcc47.log
The last lines of the build log are at the end of this report.
Some hints on fixing these issues can be found at
http://gcc.gnu.org/gcc-4.7/porting_to.html
To build with GCC 4.7, either set CC=gcc-4.7 CXX=g++-4.7 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

Hi,
libv8 builds fine with gcc 4.7.
Closing it since 3.8.9.20 will replace 3.7.12.22.
Jérémy.
