Boost. 1.91.0 regression: optional<bool> copy constructor broken #146
Description
Consider the following code:
const boost::optional<bool> constValue;
assert(!constValue.has_value()); // succeeds
boost::optional<bool> mutableValue(constValue);
assert(!mutableValue.has_value()); // succeeds
boost::optional<bool> mutableCopy(mutableValue);
assert(!mutableCopy.has_value()); // fails
The reason is that the wrong constructor is taken for boost::optional(boost::optional&):
instead of
.
