Hi, I just bumped into this bug with MinGW-4.8, which treats this as an
I use boost-1.54
My simple test case is:
typedef boost::mpl::integral_c<int,0x7fffffff>::type next_ovf;
typedef boost::mpl::integral_c<int,0x80000000>::type prior_ovf;
I worked around my test by doing changing linest 74-75 of
+ 1)) ) next;
- 1)) ) prior;
This only moves the problem from int to intmax_t, but the workaround works
for me ATM. Could this please be fixed?
I had this idea of fixing it by providing specializations of integral_c for
the limits cases? And the specializations wouldn't typedef the offending
next or prior. Would that work?
I'd have tried that myself, but this integral_wrapper.hpp file and it's
macros scared me away from this idea ;-)
