I see.
Therefore, in other terms, Nathan's analysis (see audit trail) could be

Well, before these messages of yours, we agreed (see audit trail) that
the problem had
to do with numeric_limits<double>::infinity. Indeed, gcc-3.3 (improved
in this area)
performed much better and also 2.95.x, which has a work around, did so:
this seemed
to confirm Nathan's analysis.

Now, what should we do? Do you believe boost/random or its configury
machinery are
to blame or libstdc++-v3 as shipped with gcc-3.2 and gcc-3.3?

Just in case, I'm CC-ing Nathan (Nathan, is all about libstdc++/6718
which you triaged).

Ciao, Paolo.
