Re: [Boost-users] [heap] Boost heap and default constructors for comparators

The Boost heap library (at least binomial and fibonacci heaps) requires a default constructor of its comparator in order to call 'pop()' on a heap.

I ran into this because I was trying to use a std::binary_negate<> wrapper around another comparator: this has no default constructor. So it's pretty easy to work around; I just have to provide a custom version of binary_negate.

However, is this intentional? Should it be fixed?

this should be fixed (not sure if it will make it into 1.49, as it is supposed to be released in a few days ... cheers, tim
