12044,Passing -Ofast to pathscale toolchain is unsafe and break stuff,Michał Górny <mgorny@…>,Vladimir Prus,"When attempting to bootstrap boost-build with pathscale toolset, the build fails with internal compiler problem. It turns out it happens because of `-Ofast` being passed to the compiler.

It is unclear to me why `-Ofast -O3` is being used there (no other toolset does that) but it sounds like a really bad idea. Besides to triggering compiler bugs like the one mentioned there, it also enables various insecure optimizations.

Please consider 'lowering' the flags down to regular `-O3`. I'm attaching a bootstrap.log with the failure and a proposed patch.",Bugs,closed,To Be Determined,build,Boost Development Trunk,Problem,fixed,,
