array subscript is above array bounds warning

[tfogal at sci -- utah.edu]

I am seeing this warning while running ../bjam from within the tools directory:

gcc.compile.c++ ../bin.v2/libs/test/build/gcc-4.3.2/release/link-static/debug.o
In file included from ../libs/test/src/debug.cpp:16: /usr/include/c++/4.3/bits/stl_algo.h: In function `char* boost::debug::<unnamed>::prepare_window_title(const boost::debug::dbg_startup_info&)':
/usr/include/c++/4.3/bits/stl_algo.h:190: warning: array subscript is above array bounds

I would normally ignore such things, as it's "just a warning".. but this seems like the kind of warning which should really be an error.

Replace the "--" with a dot in my email, of course.

This is a spurious warning caused by loop unrolling in std::find. There's nothing we can do about it.

Possible workaround if you're stuck with a broken compiler:

$ diff -u boost_1_47_0/boost/test/impl/debug.ipp install_1_47_0/include/boost/test/impl/debug.ipp
