I've found the following bug in program_options:

When printing the options syntax, if it doesn't fit in one line, the library crashes.

At what line and with what diagnostics?

Here is a minimal reproduction:

options_description opts;

opts.add_options()("option", "A very long description. A very long description. A very long description. A very long description. A very long description.");

cout << opts;

I work on XP professional x64 SP1 and use Boost 1.33.1

Please try 1.34.1 -- a similar bug was fixed there. - Volodya
