Re: [Quantlib-dev] Compiler bug in Market Models???

[Joseph W. <jo...@gn...>]

Doing some more googling, it turns out that this really does require a=20
language lawyer, since it involves an issue in the C++ standard, that the=20
standards committee not resolved yet.

See

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D57

for the gory details.  The g++ have a patch that will parse the code, but t=
hey=20
haven't applied it yet pending a decision of the C++ standards committee.
