--- Comment #5 from Thomas Markwalder <tmark at isc dot org> ---
A bit more digging reveals that in the logic expression which fails:
{{{
// Check if we need to run the operation again.
if (ec == boost::asio::error::would_block
|| ec == boost::asio::error::try_again)
return false;
}}}
The value for error_category:m_cat differs between the implicitly created
instances for would_block and try_again.
If one splits the if into two separate if statements, the values for m_cat are
the same. This looks a like the behavior described under "Static Variables in
Inline Functions" described here:
