Re: [Quantlib-users] Exception running EuropeanOption example (maybe boost problem?)

[Bojan N. <bo...@bn...>]

This does look like to be a bug in boost on your platform/compiler
combination. The std::transform takes a copy of the function (i.e.,
fourth) argument and boost seems to trip up when it is time to destroy
it.

I would try expanding out the transform code in the leastsquares
code. Something as simple as below should do I think as a first check.

Best,
Bojan
